Detailed Description
The embodiments of the present invention will be described below with reference to the drawings.
Fig. 1 is a flowchart illustrating a method for data conversion processing according to an embodiment of the present invention. As shown in fig. 1, the method includes:
step 101: acquiring a target courseware to be converted uploaded by a client, and determining the corresponding maximum conversion time according to the attribute information of the target courseware; the attribute information includes a courseware type and/or a courseware size.
In the embodiment of the invention, the data conversion processing method is executed by a conversion server capable of converting courseware. When a user (such as a teacher) needs to convert a courseware, the user can upload the courseware to the conversion server through the client, and the courseware is called a target courseware. In addition, courseware, including target courseware, has corresponding attribute information, and the attribute information is concrete courseware type, courseware size, etc. The courseware type can be determined according to the format of courseware, such as text type, audio type, picture type and the like; the courseware size is the storage space occupied by the courseware. After determining the attribute information of the target courseware, the maximum transition duration of the target courseware may be determined. In general, the larger the courseware size is, the larger the maximum conversion time length is; different courseware types generally have different maximum transition durations due to the possibility of using different transition strategies or performing transitions based on different third party services.
Step 102: target courseware is added to the conversion queue, and the conversion queue is a queue at the head of the queue, wherein the courseware can be converted.
In the embodiment of the invention, as the conversion server may need to convert a plurality of courseware, the conversion server is provided with a conversion queue, the conversion queue is used for storing the courseware to be converted, and the conversion queue is essentially a queue, i.e. first in first out, the courseware stored in the conversion queue first can be taken out first for conversion, i.e. the courseware at the head of the queue in the conversion queue can be converted. And after the conversion server receives the target courseware, storing the target courseware into the corresponding conversion queue according to the sequence.
Step 103: and when the target courseware is positioned at the head of the conversion queue, generating a target process for converting the target courseware, and determining the conversion starting time of the target courseware.
In the embodiment of the invention, after the target courseware is added into the conversion queue, because the courseware at the head of the conversion queue can be converted, other courseware before the target courseware can be sequentially converted in the conversion queue; and when the target courseware is positioned at the head of the conversion queue, converting the target courseware. Specifically, the conversion server generates a process for converting the target courseware, i.e. a target process, and also determines a conversion start time of the target courseware, i.e. a time (server time) when the target process starts to convert the target courseware.
Step 104: and if the difference between the current time and the conversion starting time is not less than the maximum conversion time length and the target process is converting the target courseware, ending the target process, deleting the target courseware from the conversion queue, adding the target courseware to a retry queue different from the conversion queue, and converting the target courseware based on the retry queue.
In the embodiment of the invention, the target process is used for converting the target courseware, and after the target process is generated, the target process can convert the target courseware. Because the target courseware has a certain size, i.e. the courseware size has a certain value, the target course generally needs a period of time to completely convert the target courseware into the required courseware, such as H5 courseware. In this embodiment, a maximum conversion time length is preset, where the maximum conversion time length is greater than a theoretical time length for a target course to convert the target courseware (for example, an average value of conversion time lengths of previous course conversion similar to the target courseware, etc.), that is, in a normal situation, a time length required for successfully converting the target courseware is less than the maximum conversion time length. If the target process successfully converts the target courseware, the difference between the current time of the conversion server and the conversion starting time is smaller than the maximum conversion time length, that is, the time length for converting the target courseware is smaller than the maximum conversion time length, and the target process normally completes the conversion processing process.
Conversely, if the difference between the current time and the starting conversion time is not less than the maximum conversion time and the goal process is performing the conversion processing on the goal courseware, it indicates that the goal process has not successfully converted the goal courseware within the time of the maximum conversion time, which may be that the courseware size of the goal courseware is too large to complete the conversion process in a short time; or the third party service required in the conversion process is abnormal, so that the target courseware is not successfully converted currently. At this time, the target courseware is deleted from the conversion queue and is added to other queues different from the conversion queue, namely a retry queue; the retry queue in this embodiment is a queue that is set separately and is used to store an abnormal target courseware, and then perform conversion processing on the target courseware in other manners until the target courseware is successfully converted. Meanwhile, after the target courseware is deleted from the conversion queue, other courseware behind the target courseware is located at the head of the conversion queue, and then other courseware behind the target courseware can be converted, so that the conversion processing process of the subsequent courseware is not influenced. In addition, the target process also needs to be ended, and due to the one-to-one correspondence between the processes and the courseware, when the target courseware cannot be converted in time, the corresponding target process can be conveniently stopped, and the conversion of other courseware is not influenced.
Optionally, the method further comprises: and when the target courseware is successfully converted, feeding back a conversion success message to the client. Specifically, if the target course completes the conversion of the target courseware, and the difference between the current time and the conversion starting time is less than the maximum conversion time, it is indicated that the conversion of the target courseware is completed within the maximum conversion time, that is, it can be determined that the target courseware is successfully converted; in addition, the target process is ended and the target courseware is deleted from the conversion queue. Alternatively, if the target courseware is moved to the retry queue, if the target courseware in the retry queue is successfully converted, it can also be determined that the target courseware is successfully converted, and a conversion success message is fed back to the client.
The data conversion processing method provided by the embodiment of the invention determines the corresponding maximum conversion duration when the target courseware needs to be converted, and converts the target courseware by generating the target processes corresponding to one; if the target courseware can not be successfully converted within the time of the maximum conversion duration, the target courseware is transferred from the conversion queue to the retry queue, so that the next courseware in the conversion queue can be converted, the conversion process of the subsequent courseware is not influenced by the excessive time occupied by the abnormal target courseware, and the blockage of the conversion queue can be avoided; and when the target courseware can not be converted in time, the one-to-one corresponding target process can be conveniently stopped, and the target process can not influence the conversion of other courseware.
On the basis of the embodiment, the courseware uploading and courseware conversion of the client are executed asynchronously, namely, the courseware is converted after the courseware uploading is successful. In an embodiment of the present invention, the step 101 of "obtaining a target courseware to be converted uploaded by a client" includes:
step A1: and receiving an uploading request initiated by the client, wherein the uploading request is used for uploading the target courseware to be converted.
Step A2: and after the target courseware is successfully received, determining to obtain the target courseware, and feeding back an uploading success message to the client.
In the embodiment of the invention, the client uploads the target courseware to the conversion server by initiating an uploading request; after receiving the complete target courseware, the conversion server confirms that the target courseware is successfully received, and at the moment, the target courseware can be obtained. And the conversion server feeds back an upload success message to the client to inform the client. According to the embodiment, the processes of uploading and conversion are asynchronously executed, so that the phenomenon that the conversion process is meaningless due to the fact that the conversion is directly carried out due to unsuccessful uploading can be avoided. In addition, when the target courseware is added to the conversion queue in step 102, the target courseware is added according to the time sequence of successful uploading of the target courseware, that is, the courseware successfully uploaded is preferentially added.
Optionally, the attribute information of the courseware includes a courseware type and a courseware size, and the embodiment determines the corresponding maximum conversion time based on the courseware type and the courseware size of the target courseware. Specifically, the step 101 "determining the corresponding maximum conversion time length according to the attribute information of the target courseware" includes:
step B1: and determining historical courseware with the same courseware type as the target courseware, wherein the historical courseware is the courseware which is successfully converted.
In the embodiment of the invention, since the conversion time lengths of courseware of different courseware types may be different, the embodiment determines the maximum conversion time length of the target courseware based on historical courseware which has the same courseware type and is successfully converted. Specifically, the present embodiment predicts the conversion duration of the successful conversion of the target courseware, i.e. the successful conversion prediction duration, and then determines the maximum conversion duration of the target courseware based on the successful conversion prediction duration.
Step B2: and taking the historical courseware of which the difference between the courseware size and the courseware size of the target courseware is smaller than a preset value as effective historical courseware, performing regression analysis on the courseware sizes of the effective historical courseware and the successful conversion time length, and determining the change rate between the courseware sizes and the successful conversion time length.
Because the courseware sizes of the target courseware and the historical courseware are difficult to be the same, the successful conversion prediction time of the target courseware is difficult to be accurately determined directly according to the successful conversion time of the historical courseware. Further, although the larger the courseware size, the longer the successful transition duration is, in general, the two are not necessarily in a linear positive correlation, i.e. it is difficult to accurately determine the relationship between courseware size and successful transition duration.
In the embodiment of the invention, the historical courseware with the difference value between the courseware size and the courseware size of the target courseware smaller than the preset value is taken as the effective historical courseware, namely, the difference value between the courseware size of the effective historical courseware and the courseware size of the target courseware is smaller than the preset value, so that the courseware sizes of the effective historical courseware and the target courseware are basically similar, and the courseware sizes of all the effective historical courseware can be restricted in a smaller value range. Since the value range is relatively small, the courseware size and the successful conversion time length are basically in a linear relation in the value range, so that the change rate between the courseware size and the successful conversion time length can be accurately determined by performing regression analysis (linear regression analysis) on the courseware sizes and the successful conversion time lengths of a plurality of effective historical courseware. The "difference between a and B" in the present embodiment refers to the absolute value of a-B.
Step B3: and correcting the courseware size of the effective historical courseware to be the same as the courseware size of the target courseware, and determining the successful conversion time length after the effective historical courseware correction according to the change rate.
In the embodiment of the invention, the courseware size of the effective historical courseware is generally different from the courseware size of the target courseware, so that the required success conversion prediction time length cannot be determined directly through the success conversion time length of the effective historical courseware. In this embodiment, the courseware size of the effective historical courseware is corrected to be the same as the courseware size of the target courseware, so that the corrected effective historical courseware and the target courseware have the same attribute information, that is, the courseware type and the courseware size are the same. Meanwhile, the successful conversion duration of the effective historical courseware also required to be synchronously corrected. As described in step B2 above, since there is a linear positive correlation between the courseware size and the successful transition duration, the successful transition duration can be corrected synchronously according to the rate of change between the courseware size and the successful transition duration.
Alternatively, it is provided that,
for the corrected successful transition duration for the ith active history courseware,
for the successful transition duration of the ith active history courseware,
for the courseware size of the ith active history courseware,
the courseware size for the target courseware, and k is the rate of change between courseware size and the length of time of successful transition. The correction degree of the courseware size in the correction process
Degree of correction of successful conversion duration
The two are also in linear relation, and the change rate between the two is also k, so
. Therefore, the successful conversion time length after the correction of the effective historical courseware is as follows:
. In this embodiment, the change rate is a ratio of a change amount of the successful conversion time length to a change amount of the courseware size.
Step B4: and taking the average value of the corrected successful conversion durations of the plurality of effective historical courseware as the successful conversion prediction duration of the target courseware, and taking the product of the successful conversion prediction duration and the adjustment coefficient and the smaller value of the preset maximum value as the maximum conversion duration of the target courseware, wherein the adjustment coefficient is more than 1.
In the embodiment of the invention, after the effective historical courseware is corrected, the successful conversion time length after the effective historical courseware is corrected can represent the time length required by the successful conversion of the target courseware, and the successful conversion prediction time length of the target courseware can be more accurately determined by averaging a plurality of corrected successful conversion time lengths. When the target courseware is converted, reasonable reasons inevitably exist to cause the conversion rate to be slower, so the adjustment coefficient is multiplied on the basis of the successful conversion prediction time length, and the maximum conversion time length of the target courseware is determined based on the final product. The adjustment coefficient is a value larger than 1, and specifically may be 1.5, 2, or the like.
In addition, in order to avoid setting an excessively large maximum conversion time length for a large courseware size, a maximum value is also preset in the embodiment, that is, the maximum value is preset, that is, the conversion time lengths of all courseware cannot exceed the preset maximum value. Specifically, the smaller value of the product of the prediction time length of successful conversion and the adjustment coefficient and the preset maximum value is used as the maximum conversion time length of the target courseware. For example, the prediction duration for successful transition is
The adjustment coefficient is
If the preset maximum value is MAX, the maximum conversion time length of the target courseware is MAX
。
According to the embodiment of the invention, the value range of the courseware size of the effective historical courseware is restricted in a smaller range through the difference value of the courseware size is smaller than the preset value, and the courseware size and the successful conversion time length in the range basically accord with a linear relation, so that the effective historical courseware with different courseware sizes can be corrected to be the same as the courseware size of the target courseware, the corrected successful conversion time length is determined, the successful conversion prediction time length of the target courseware can be accurately determined, and the accuracy of the maximum conversion time length is improved; and the maximum value of the maximum conversion time length can be further limited by presetting the maximum value, so that the phenomenon that the overlarge maximum conversion time length is set for the larger courseware size can be avoided, and other courseware can be ensured to be converted in time.
On the basis of the above embodiment, the method further includes:
step C1: the maximum queue length of the conversion queue is preset.
Step C2: and if the current queue length of the conversion queue is larger than the maximum queue length, carrying out capacity expansion processing, and transferring part of courseware in the conversion queue to a server after capacity expansion for processing.
In the embodiment of the invention, when the number of courseware uploaded by one or more clients is large, the conversion queue of the conversion server is too long, and at the moment, courseware behind the conversion queue can not be converted in time. The present embodiment also sets a limit for the conversion queue, i.e., sets a maximum queue length. If the current queue length of the conversion queue is smaller than the maximum queue length, the process is normally executed, and the newly received courseware can be added into the conversion queue. If the current queue length of the conversion queue is greater than the maximum queue length, it is indicated that the conversion queue is too long, and there may be a large number of courseware to be converted at this time. The queue length (including the current queue length and the maximum queue length) may be the number of courseware in the conversion queue, or the sum of the courseware sizes of all courseware in the conversion queue.
The method for data conversion processing provided by the embodiment of the present invention is described above in detail, and the method can also be implemented by a corresponding apparatus.
