Technical Field

Background

With the increasing functions of information systems, a single system cannot support the implementation of all functions, and a common scheme is to form independent function modules into subsystems, and the subsystems are mutually called in an RPC (Remote Procedure Call) manner to achieve the purpose of decoupling. In particular, the micro service Architecture (micro service Architecture) popular in recent years pushes the solution extremely, and each function point may become a small API (Application Programming Interface) service module. In this context, each API call may be a service completed by several levels or dozens of service modules working together, and the call across systems becomes a main cause of time consumption of the service.

Therefore, how to reduce the service time consumption caused by cross-system calling under the micro-service framework to improve the service efficiency under the micro-service framework is a problem to be solved at present.

FIG. 1 is a flow chart of one embodiment of a caching method of the disclosed microservice system. As shown in fig. 1, the method of this embodiment may be applied to a first micro service module in a micro service system, including:

step 102, in response to that the first micro service module needs to acquire target data in the storage system, determining whether a target instruction matching the target data exists in an instruction cache region of the first micro service module.

In the embodiment of the present disclosure, the micro service system may include a first micro service module and a second micro service module, and may further include other micro service modules, a storage system of the micro service system may be a cache system, a centralized storage system, or a distributed storage system, the number of the micro service modules included in the micro service system and the type of the storage system are not specifically limited in the embodiment of the present disclosure, and the micro service module in the embodiment of the present disclosure may also be referred to as a micro service subsystem.

In the embodiment of the disclosure, various information such as data, instructions, files, images and the like can be mutually transmitted among all the micro service modules in the micro service system. In any information transmission process, the micro service module initiating the information transmission request may be referred to as an upstream micro service module (also referred to as a client, or a client micro service module), and the micro service module responding to the information transmission request may be referred to as a downstream micro service module (also referred to as a server, or a server micro service module). The first micro service module in step 102 may be any upstream micro service module in the micro service system, and the second micro service module may be any downstream micro service module in the micro service system.

In the embodiment of the present disclosure, each micro service module in the micro service system may only support data caching, may only support instruction caching, and may also support data caching and instruction caching. The data cache may store various data such as database data, text data, image data, and the like in the data cache region, the instruction cache may store an instruction (also referred to as an operation instruction) and an access parameter corresponding to the instruction in the instruction cache region, where the instruction may be various instructions such as a database operation instruction, a text operation instruction, an image operation instruction, and the like, and the corresponding access parameter may be various access parameters such as an access parameter for accessing the database, an access parameter for accessing the text, an access parameter for accessing the image, and the like.

In the embodiment of the present disclosure, when the first micro service module needs to acquire target data in the storage system, it may be determined whether a target instruction matching the target data exists in an instruction cache region of the first micro service module. The target data may be any of database data, text data, image data, and the like in the storage system. The target instruction that matches the target data is an instruction used to retrieve the target data from the storage system.

And 104, if the target instruction exists in the instruction cache region, acquiring an access parameter corresponding to the target instruction from the instruction cache region.

In the embodiment of the present disclosure, the target instruction in the instruction cache region of the first micro service module and the access parameter corresponding to the target instruction may be received from the second micro service module and cached in the instruction cache region before the first micro service module acquires the target data this time. It should be noted that the access parameter corresponding to the target instruction may include an access address, and/or an access key. The access Address may include a device IP Address (Internet Protocol Address) of a device where the storage system is located. In the case where the target data is database data, the access address may further include a database port number. The access key may include a user name and a user password for accessing the device in which the storage system is located.

In step 104, if the determination result in step 102 indicates that the target instruction exists in the instruction cache region of the first micro service module, the access parameter corresponding to the target instruction may be obtained from the instruction cache region, and further, the data may be obtained from the storage system by using the target instruction and the access parameter.

And step 106, accessing the storage system based on the access parameters, and acquiring target data from the storage system by using the target instruction.

In the embodiment of the present disclosure, the storage system may be a distributed KV (Key-data Key-Value) system, the data storage medium of the storage system may be a finite set such as db (database), Redis (Remote Dictionary service), and a distributed cache system (MemCache), and the target instruction for acquiring the target data from the storage system is the same regardless of which micro service module in the micro service system executes the acquired target data. The target instruction can thus be passed to the first microserver module, execution of which by the first microserver module obtains the same value, while the level of invocation can be reduced.

Based on the target command and the access parameter obtained in step 104, in this step 106, the first microserver module may access the storage system based on the access parameter and obtain the target data from the storage system by using the target command.

As an example, the target data may be student name data C, which may be stored in a student achievement table B in a database a in the storage system, which is the device D. The target instruction, that is, the instruction used to obtain the target data FROM the storage system, is "SELECT C FROM B", and the access address in the access parameter may include an IP address of a device D where the storage system is located and a port number of the data a. The first micro-service module can access the database A in the device D based on the access address, and acquires the student name data C in the student information table B FROM the database A by using a target instruction 'SELECT C FROM B'.

Based on the caching method of the micro service system provided by the above embodiment of the present disclosure, for a first micro service module and a second micro service module located in the micro service system, when the first micro service module needs to acquire target data in the storage system, it is first determined whether a target instruction matching the target data exists in an instruction cache region of the first micro service module, if the target instruction exists in the instruction cache region, an access parameter corresponding to the target instruction is acquired from the instruction cache region, where the access parameter includes an access address, and then the access parameter is used to access the storage system, and the target instruction is used to acquire the target data from the storage system. Therefore, the instruction cache of the micro-service system is realized, the first micro-service module can directly acquire the target data from the storage system by using the target instruction and the access parameter in the instruction cache region, and compared with the method for acquiring the target data by calling the second micro-service module, the time consumed by the micro-service system can be effectively reduced, and the service efficiency of the micro-service system is improved. In addition, when the first micro service module needs the target data, the current target data can be acquired from the storage system by using the target instruction and the access parameter, and the cache target data is acquired from the data cache region relative to the cache target data, so that the effectiveness and the accuracy of the data are improved.

Optionally, in some possible implementations of the present disclosure, the first micro service module may receive a third obtaining request sent by a third micro service module for obtaining the target data, and in response to that the third micro service module belongs to the micro service system, the first micro service module may determine, according to a third switch parameter included in the third obtaining request, whether the third micro service module supports the instruction cache, and in response to that the third micro service module does not support the instruction cache, the first micro service module may send the target data to the third micro service module; in response to the third micro service module supporting the instruction cache, the first micro service module may send the target instruction and the access parameter to the third micro service module, so that the third micro service module obtains the target data based on the target instruction and the access parameter.

In the embodiment of the disclosure, the first micro service module may transmit the target instruction and the access parameter returned by the second micro service module to the upstream micro service module, so that the upstream micro service module may also obtain the target data from the storage system based on the target instruction and the access parameter, which is beneficial to reducing the load of the entire system.

In this embodiment of the disclosure, the first micro service module may receive a third acquisition request sent by a third micro service module for acquiring the target data, where the third micro service module may be any one of the other micro service modules in the micro service system except the first micro service module and the second micro service module, or may be any one of the other micro service modules in the micro service system except the micro service system.

In this embodiment of the disclosure, the third obtaining request sent by the third micro service module includes a third switch parameter for identifying whether the third micro service module supports instruction caching. Under the condition that the third micro service module belongs to the micro service system, the first micro service module can determine whether the third micro service module supports instruction caching according to the third switch parameter, and if the third micro service module does not support instruction caching, the first micro service module can send target data to the third micro service module; if the third micro service module supports instruction caching, the first micro service module may send the target instruction and the access parameter to the third micro service module, so that the third micro service module obtains the target data based on the target instruction and the access parameter.

It should be noted that, when sending the target data to the third micro service module, the first micro service module may send the target data acquired from the data cache region of the first micro service module to the third micro service module, or send the latest target data acquired from the storage system by using the target instruction and the access parameter corresponding to the target instruction to the third micro service module.

Based on the possible implementation manner, when the third micro service module belonging to the micro service system requests the first micro service module to acquire the target data, the first micro service module may determine to send the target data to the third micro service module or send the target instruction according to whether the third micro service module supports the instruction cache, and when sending the target data, may send the target data in its own data cache region, and may also send the latest acquired target data, which has better compatibility and applicability, and may effectively avoid resource waste caused by sending the target instruction to the third micro service module when the third micro service module does not support the instruction cache.

Optionally, in some possible implementations of the disclosure, if the third micro service module does not belong to the micro service system, the first micro service module may determine, according to the pre-configuration information, whether itself is allowed to send the instruction to another micro service system other than the micro service system, and determine, according to the third switch parameter, whether the third micro service module supports the instruction cache, and if the first micro service module is allowed to send the instruction to another micro service system other than the micro service system and the third micro service module supports the instruction cache, the first micro service module may send the target instruction and the access parameter to the third micro service module, so that the third micro service module obtains the target data based on the target instruction and the access parameter; if the first micro service module is not allowed to send the instruction to other micro service systems except the micro service system, the first micro service module may send the target data to the third micro service module.

In this possible implementation manner, in a case that the third micro service module does not belong to the micro service system, in consideration of data security, the first micro service module may determine whether the first micro service module is allowed to send the instruction to another micro service system other than the micro service system according to the pre-configuration information, and whether the third micro service module supports instruction caching, if the third micro service module supports instruction caching and is allowed to send, the third micro service module may send the target instruction and the access parameter corresponding to the target instruction to the third micro service module, so that the third micro service module obtains the target data based on the target instruction and the access parameter, and if the third micro service module is not allowed to send, the third micro service module may send the target data to the third micro service module. It should be noted that, an implementation manner of the third micro service acquiring the target data based on the target instruction and the access parameter is the same as an implementation manner of the first micro service module acquiring the target data based on the target instruction and the access parameter, and reference may be specifically made to the description of the first micro service module acquiring the target data based on the target instruction and the access parameter in the foregoing embodiment.

Based on the possible implementation manner, for the third micro service module not belonging to the micro service system, the first micro service module can only send the target instruction and the access parameter corresponding to the target instruction to the third micro service module under the condition that the pre-configuration information allows the first micro service module to send the instruction to other micro service systems except the micro service system and the third micro service module supports instruction caching, so that the data security of the micro service system can be effectively ensured.

Optionally, in some possible implementation manners of the present disclosure, the access parameter may further include an expiration policy, the first micro service module may determine whether the target instruction in the instruction cache region is in an effective state based on the expiration policy, and if the target instruction is not in the effective state, may release a storage space occupied by the target instruction and the access parameter in the instruction cache region, so as to avoid waste of the storage space by the target instruction and the access parameter in the invalid state, and help to save the storage space.

Optionally, in some possible implementations of the present disclosure, the expiration policy includes any one of: effective access duration and effective use times. The Second micro service module may configure an expiration policy for the target instruction according to a QPS (Query Per Second) of the micro service system.

Under the condition that the QPS of the micro-service system is low, the second micro-service module can determine that the expiration policy of the target instruction is the effective access duration, namely the target instruction is in an effective state in the effective access duration, and the target instruction is in a failure state when the effective access duration exceeds the effective access duration. The initial calculation time of the effective access duration may be time for the second micro service module to complete the configuration of the expiration policy, may also be time for the first micro service module to receive the target instruction, and may also be time for the first micro service module to complete the caching of the target instruction.

Under the condition that the QPS of the micro service system is high, the second micro service module may determine that the expiration policy of the target instruction is the number of effective uses, that is, the number of times that the first micro service module uses the target instruction may not exceed the number of effective uses. The number of times that the first micro service module uses the target instruction may include the number of times that the first micro service module itself uses the target instruction, and the number of times that other micro service modules that acquire the target instruction from the first micro service module use the target instruction. The effective use times may be set according to actual needs or according to QPS, and the embodiment of the present disclosure does not specifically limit the effective use times.

Or, in other possible implementation manners of the present disclosure, the second micro service module may further determine that the expiration policy of the target instruction includes two items, namely an effective access duration and an effective usage number, and within the effective access duration and without exceeding the effective usage number, the target instruction is in an effective state; and exceeding the effective access time length or exceeding the effective use times, and enabling the target instruction to be in a failure state.

Based on the possible implementation manners, the second micro service module can configure a reasonable expiration policy for the target instruction according to the QPS of the micro service system, can effectively ensure the accuracy and reliability of the target instruction, and can timely find the target instruction in the failure state, so that the storage space occupied by the target instruction and the access parameter in the instruction cache region can be released, the waste of the storage space by the target instruction and the access parameter in the failure state can be avoided, and the storage space saving is facilitated.

Optionally, in some possible implementation manners of the present disclosure, if the target instruction is not in the valid state, the first micro service module may send a third obtaining request for updating the target instruction to the second micro service module, and update the target instruction and the access parameter in the instruction cache region by using a new target instruction and a new access parameter returned by the second micro service module for the third obtaining request.

In this possible implementation manner, if the target instruction is not in an effective state, the first micro service module may send a third obtaining request for updating the target instruction to the second dimensional service module, and include target data matched with the target instruction that needs to be updated in the third obtaining request, so that the second micro service module may determine, according to the target data included in the third obtaining request, a new target instruction matched with the target data and a new access parameter.

For example, the target data may be student name data C, which is stored in a student score table B in a database a in the storage system, and the device in which the storage system is located is a device D. The target instruction is "SELECT C FROM B", and the access address in the access parameter includes the IP address of device D and the port number of data a.

In one system upgrading transformation, the database A is transplanted to the device E FROM the device D, the student name data C is transplanted to the student information table F FROM the student achievement table B, therefore, the new target instruction is 'SELECT C FROM F', and the access address in the access parameter comprises the IP address of the device E and the port number of the data A. After receiving the third acquisition request of the first micro service module, the second micro service module returns a new target instruction ("SELECT C FROM F") and new access parameters (the IP address of the device E and the port number of the data a) for the third acquisition request, so that the first micro service module updates the target instruction and the access parameters in the instruction cache region using the new target instruction and the new access parameters.

Based on the possible implementation manner, when the target instruction in the instruction cache region is not in the valid state, the first micro service module may update the target instruction and the access parameter in the instruction cache region by sending a third obtaining request to the second micro service module to obtain a new target instruction and a new access parameter. Therefore, the target instruction and the access parameter can be updated in time, and the effectiveness and the accuracy of the target instruction and the access data are improved.

Optionally, in some possible implementation manners of the present disclosure, in step 106, when the first micro service module accesses the storage system based on the access parameter and acquires the target data from the storage system by using the target instruction, the first micro service module may access the proxy layer of the storage system based on the access parameter and further receive the target data, which is returned by the proxy layer and acquired from the storage system by using the target instruction.

In the embodiment of the present disclosure, the second micro service module may output the target instruction to the first micro service module that requests the second micro service module to obtain the target data, and the first micro service module may output the target instruction to another micro service module that requests the first micro service module to obtain the target data, that is, the plurality of micro service modules in the micro service system may obtain the target data from the storage system by using the target instruction, and the storage system needs to perform access authorization on the plurality of micro service modules.

Based on this, in order to ensure the data security of the storage system and enable each micro service module to obtain the target data, a proxy layer of the storage system may be constructed, each micro service module may access the proxy layer, and the proxy layer returns the target data to each micro service module after obtaining the target data from the storage system by using the target instruction. Therefore, a safety barrier can be established for the storage system through the agent layer, each micro-service module can access the storage system through the agent layer, the data safety problem caused by the fact that each micro-service module directly accesses the storage system to obtain target data is avoided, and the safety of the data can be effectively guaranteed.

Fig. 3 is a schematic diagram of a proxy layer in the caching method of the microservice system of the present disclosure. In fig. 3, an upstream micro service module may correspond to a first micro service module in an embodiment of the present disclosure, a downstream micro service module may correspond to a second micro service module in an embodiment of the present disclosure, a cache system may correspond to a storage system in an embodiment of the present disclosure, and a cache proxy layer may be a proxy layer of the storage system in an embodiment of the present disclosure.

As shown in fig. 3, the downstream microservice module may access the caching proxy layer through a key. When the downstream microservice module returns the target instruction and the access parameter to the upstream microservice module, the access address of the caching agent layer and the key to access the caching agent layer may be included in the access parameter. The access address of the caching proxy layer may be an IP address of a device where the caching proxy layer is located, and the key for accessing the caching proxy layer may be a temporary key obtained by cloning a key for accessing the caching proxy layer by the downstream micro-service module. The upstream microservice module can access the caching proxy layer based on the access parameter, and further receive target data which is returned by the caching proxy layer and is obtained from the caching system by using the target instruction.

FIG. 2 is a flow chart of another embodiment of a caching method of the disclosed microservice system. As shown in fig. 2, on the basis of the embodiment shown in fig. 1, in response to that no target instruction exists in the instruction cache of the first microservice module, the method may further include:

step 108, the first micro service module sends a first obtaining request for obtaining the target data to the second micro service module.

In this step 108, the first micro service module may send a first obtaining request for obtaining the target data to the second micro service module when the target instruction does not exist in the instruction cache region of the first micro service module, and the first obtaining request includes a first switch parameter for identifying that the first micro service module supports the instruction cache.

After receiving the first acquisition request of the first micro service module, the second micro service module may determine whether to return the target instruction and the access parameter corresponding to the target instruction to the first micro service module according to a first switch parameter included in the first acquisition request. Here, the first switch parameter identifies that the first micro service module supports instruction caching, and the second micro service module may return the target data, the target instruction, and the access parameter to the first micro service module. The access parameter may include an access address, an access key, and an expiration policy.

Optionally, in some possible implementations of the present disclosure, if the target data is a value that can be directly obtained from the storage system, in a case that the first micro service module supports instruction caching, the second micro service may return the target data, the target instruction, and the access parameter to the first micro service module; if the target data is a value obtained by reprocessing a value directly obtained from the storage system by the second micro-service module, the second micro-service module only returns the target data to the first micro-service module and does not return a target instruction and an access parameter under the condition that the first micro-service module supports instruction caching, so that the accuracy of the data obtained by the first micro-service module is ensured.

And step 110, receiving first information returned by the second micro service module aiming at the first acquisition request.

In step 110, the first information includes the data that the second micro service module determined in step 108 needs to return to the first micro service module. Since the first switch parameter in the first get request identifies that the first micro service module supports instruction caching, the first information may include target data, a target instruction, and an access parameter.

And step 112, analyzing the first information to obtain target data, a target instruction and an access parameter, and storing the target instruction and the access parameter in an instruction cache region.

In step 112, after receiving the first information sent by the second micro service module, the first micro service module analyzes the first information to obtain data returned by the second micro service module. Under the condition that the first micro-service module supports instruction caching, the first micro-service module can obtain target data, a target instruction and an access parameter by analyzing the first information, and can store the target instruction and the access parameter in an instruction cache region so as to be used in a subsequent target data requesting process.

Based on the cache method of the micro service system provided by another embodiment of the present disclosure, in the case that the first micro service module supports instruction caching, the first micro service module may send a first get request containing a first switch parameter to the second micro service module, to obtain the target data, and can obtain the target data, the target instruction and the access parameter by analyzing the first information returned by the second micro service module aiming at the first obtaining request, and storing the target instruction and the access parameter in an instruction cache area, and subsequently when the target data needs to be acquired, the first micro service module can acquire the target data from the storage system by using the target instruction and the access parameter without acquiring the target data by calling the second micro service module, so that the service time consumption of the micro service system can be effectively reduced, and the service efficiency of the micro service system is improved.

Or, in other possible implementation manners of the present disclosure, in response to that no target instruction exists in the instruction cache region of the first micro service module, the first micro service module may send a second obtaining request for obtaining the target data to the second micro service module, where the second obtaining request includes a second switch parameter, and the second switch parameter is used to identify that the first micro service module does not support the instruction cache. And then the first micro-service module can receive second information returned by the second service module aiming at the second acquisition request, and analyze the second information to obtain target data.

Based on this, under the condition that the first micro service module does not support the instruction cache, the first micro service module may send a second acquisition request including the second switch parameter to the second micro service module to acquire the target data. After receiving the second acquisition request, the second micro service module may determine, according to a second switch parameter included in the second acquisition request, that the first micro service module does not support the instruction cache, and may further return second information including the target data for the second acquisition request. It can be seen that the second micro service module only returns the target data to the first micro service module and does not return the target instruction and the access parameter under the condition that the first micro service module does not support the instruction cache, which is helpful for avoiding resource waste caused by returning the target instruction and the access parameter to the first micro service module under the condition that the first micro service module does not support the instruction cache.

Optionally, in some possible implementation manners of the present disclosure, when the first micro service module receives the first information returned by the second micro service module for the first acquisition request, the first information returned by the second micro service module for the first acquisition request and encrypted based on the preset transmission key may be received. When the first micro service module analyzes the first information to obtain the target data, the target instruction and the access parameter, the first micro service module can decrypt the first information by using a preset transmission key to obtain decrypted first information; and then analyzing the decrypted first information to obtain target data, a target instruction and an access parameter.

In this possible implementation, part or all of the microservice modules in the microservice system may maintain a common pre-set transmission key. The preset transmission key may be determined according to actual needs, which is not specifically limited in the embodiment of the present disclosure.

When the second micro service module sends the first information to the first micro service module, the second micro service module can encrypt the first information based on a preset transmission key and then send the encrypted first information to the first micro service module, and after receiving the encrypted first information, the first micro service module can decrypt the encrypted first information based on the preset transmission key to obtain the decrypted first information, and then analyze the decrypted first information to obtain target data, a target instruction and an access parameter.

Based on the possible implementation mode, when each micro-service module in the micro-service system performs information transmission, encryption and decryption of transmission information can be realized based on the preset transmission key, and the safety of the information in the transmission process can be effectively ensured, so that the data safety of the whole micro-service system is improved.

Optionally, in other possible implementation manners of the present disclosure, when the first micro service module receives the first information returned by the second micro service module for the first acquisition request, the first information returned by the second micro service module for the first acquisition request and obtained by encapsulating the target data, the target instruction, and the access parameter based on the preset encapsulation function acquired from the preset class library may also be received. When the first micro-service module analyzes the first information to obtain the target data, the target instruction and the access parameter, a preset analysis function corresponding to a preset encapsulation function can be obtained from a preset class library, and then the first information is analyzed by using the preset analysis function to obtain the target data, the target instruction and the access parameter.

A Client-Server (C/S) communication mode based on a general Protocol such as HTTP (Hyper Text Transfer Protocol) may be unique to a Server or a Client. Any micro service module in the embodiments of the present disclosure may serve as a server to provide data to other micro service modules, or may serve as a client to request other micro service modules to obtain data.

Based on this, in this possible implementation manner, a preset class library commonly maintained by some or all micro service modules in the micro service system may be established, so that the class libraries of each micro service module may be updated and upgraded synchronously, and the system maintenance cost may be reduced in favor of maintaining the respective class libraries for each micro service module.

FIG. 4 is a diagram illustrating a preset class library in the caching method of the micro service system according to the present disclosure. As shown in fig. 4, the preset class library may include a server class library and a client type, the downstream micro service module may copy (Clone) the server class library from the preset class library, and the upstream micro service module may copy (Clone) the client class library from the preset class library, so as to implement information transmission between the upstream service module and the downstream module.

In this possible implementation manner, when the second micro service module returns the first information to the first micro service module in response to the first acquisition request, the second micro service module may encapsulate the target data, the target instruction, and the access parameter based on a preset encapsulation function acquired from the preset class library to obtain the first information. The first micro service module can analyze the first information by using a preset analysis function which is acquired from a preset class library and corresponds to the preset encapsulation function, so as to obtain target data, a target instruction and an access parameter.

In the preset class library, a decode function and an encapsulate function can be simultaneously realized aiming at the same operation, and each micro-service module can call the corresponding parse function or encapsulate function from the preset class library according to the function requirement of the micro-service module. The encapsulation function and the analysis function can follow the same preset protocol, the encapsulation function can encapsulate data according to the preset protocol to obtain encapsulated information, and the analysis function can analyze the encapsulated information according to the preset protocol to obtain real data.

As an example, for database operations, the preset protocol may be [ version ] [ mysql | pgsql | oracle | … ] [ IP: port ] [ database ] [ table ] [ command ], where [ version ] is a protocol version field, [ mysql | pgsql | oracle | … ] is a database type field, [ IP: port ] is an IP address and port field, [ database ] is a database identification field, [ table ] is a data table field, and [ command ] is an operation instruction field. The encapsulation function may encapsulate the database data according to the preset protocol to obtain encapsulated information, and the parsing function may parse the encapsulated information according to the preset protocol to obtain the database data.

Fig. 5 is an interaction diagram of a first micro service module and a second micro service module according to the present disclosure. The cache method of the microservice system of the present disclosure is further described below with reference to fig. 5:

in the first request process, when the first micro service module needs to acquire target data in the storage system, the first micro service module requests the second micro service module to acquire the target data; the second micro service module obtains target data from the storage system after receiving a request of the first micro service module, determines whether the first micro service module supports instruction cache, returns the target data to the first micro service module if the first micro service module does not support the instruction cache, adds a target instruction and an access parameter in the returned data if the first micro service module supports the instruction cache so as to return the target data, the target instruction and the access parameter to the first micro service module, and the first micro service module stores the target instruction and the access parameter returned by the second micro service module in an instruction cache area.

In the subsequent request process, when the first micro-service module needs to acquire target data in the storage system, accessing the instruction cache region of the first micro-service module to acquire a target instruction, and if the instruction cache region does not have the target instruction, repeating the first request process; if the target instruction exists in the instruction cache region, whether the target instruction is in an effective state is determined, if the target instruction is not in the effective state, the first request process is repeated, and if the target instruction is in the effective state, the first micro-service module accesses the storage system based on the access parameter and acquires target data from the storage system by using the target instruction.
