Fig. 2 is a kind of process of the synchronous flow method of adjustment embodiment one of data shown according to an exemplary embodiment
Figure, this method are suitable for distributed data base, which includes main memory accumulation and backup storage cluster, wherein leading
Data are synchronized to backup storage cluster and carried out by storage cluster for obtaining data from the storage log of distributed data base
Backup, wherein main memory accumulation and backup storage cluster may each comprise multiple storage mediums, and the storage that the two respectively includes is situated between
The number of matter can be different.As shown in Fig. 2, method includes:
In a step 101, the macro ratio between the main memory accumulation and the backup storage cluster is monitored.
The scale of so-called main memory accumulation and backup storage cluster refers to main memory accumulation and standby in the present embodiment
The quantity for the storage medium for including in part storage cluster.In the present embodiment between so-called main memory accumulation and backup storage cluster
Macro ratio can illustratively be interpreted as, wrapped in the quantity of the storage medium for including in main memory accumulation and backup storage cluster
The ratio of the quantity of the storage medium contained.
Wherein, in a kind of way of example, due to influencing data transmission between main memory accumulation and backup storage cluster
The factor of ability be mainly backup storage cluster in storage medium quantity, when storage medium in backup storage cluster quantity compared with
When more, can by between main memory accumulation and backup storage cluster data transmit flow rate upper limit value setting it is relatively higher,
Otherwise when the negligible amounts of storage medium in backup storage cluster, then by data between main memory accumulation and backup storage cluster
The flow rate upper limit value of transmission is arranged relatively lower, thus can mainly pass through the rule of monitoring backup storage cluster in the present embodiment
Mould situation of change (popularization or diminution) realizes the monitoring to macro ratio between main memory accumulation and backup storage cluster,
When the scale of backup storage cluster changes, then the macro ratio hair between main memory accumulation and backup storage cluster is defaulted
Changing.
In another implementation, the scale of main memory accumulation He backup storage cluster can also be supervised simultaneously
Survey, when a scale in the two changes or the two scale simultaneously occur inequality proportion change when, it is determined that two
Macro ratio before person changes.
In a step 102, when the macro ratio changes, based on preset main memory accumulation and backup storage collection
Group between macro ratio and flow rate upper limit value between corresponding relationship, adjust the data from the primary storage cluster synchronization to
The upper limit value of flow used in the backup storage cluster, so that the upper limit value matches with the macro ratio after variation.
Macro ratio in the present embodiment between so-called main memory accumulation and backup storage cluster and flow rate upper limit value it
Between corresponding relationship can according to need and set, without being confined to a certain specific corresponding relationship.Such as at one
In illustrative embodiment, corresponding flow rate upper limit can be set for each preset macro ratio, in adjustment primary storage
It, can be according to the scale between main memory accumulation and backup storage cluster when flow rate upper limit between cluster and backup storage cluster
Flow rate upper limit between main memory accumulation and backup storage cluster is adjusted to corresponding numerical value by ratio.Alternatively, another real
It applies in mode, can also be tied using the scale for backing up storage cluster as a Consideration for each preset macro ratio
The scale situation for closing backup storage cluster, is arranged corresponding flow rate upper limit value, for example, in main memory accumulation and backup storage cluster
Between macro ratio be 2 to 1, back up storage cluster scale be 50, then in the macro ratio and backup storage cluster scale
Under conditions of, flow rate upper limit can be set to the half of the scale of backup storage cluster.Certainly it is only for examples to say
Bright rather than unique restriction to the disclosure.
The present embodiment by when detecting that the macro ratio between main memory accumulation and backup storage cluster changes,
Based on the macro ratio between preset main memory accumulation and backup storage cluster and the corresponding relationship between flow rate upper limit value, adjust
The upper limit value of entire data flow used in from primary storage cluster synchronization to backup storage cluster, so that the scale after upper limit value and variation
Ratio matches.The present embodiment can be based on the macro ratio between main memory accumulation and backup storage cluster, adjust automatically number

Change, the corresponding pass based on the macro ratio between preset main memory accumulation and backup storage cluster and between flow rate upper limit value
System, adjusts the upper limit value of data flow used in from the primary storage cluster synchronization to the backup storage cluster, so that institute
Upper limit value is stated to match with the macro ratio after variation.
In scene provided in this embodiment, the data that main memory accumulation is got from log are transferred to backup storage collection
Process resource occupancy, which is lower than on the storage medium of the second preset threshold, in group carries out backup preservation.
The present embodiment is real-time or the occupancy of the process resource of each storage medium is regularly obtained from backup storage cluster
Situation, and according to the process resource occupancy situation of each storage medium, judge which storage medium is relatively idle, which storage is situated between
Matter is quite busy to handing over, when the process resource occupancy for including in backup storage cluster is lower than the storage medium of the second preset threshold
It is corresponding to adjust between main memory accumulation and backup storage cluster when the quantity of (i.e. more idle storage medium) increases or reduces
Flow rate upper limit.
It is exemplary, in the present embodiment, the macro ratio property of can be exemplified between main memory accumulation and backup storage cluster
Understanding are as follows: process resource occupancy is preset lower than second in the number of storage medium and backup storage cluster in primary storage cluster
The ratio of the number of the storage medium of threshold value.
Wherein, the present embodiment is based on the macro ratio and flow between preset main memory accumulation and backup storage cluster
Corresponding relationship between limit value adjusts the side of the upper limit value of data flow used in from primary storage cluster synchronization to backup storage cluster
Method is similar with Fig. 2 embodiment, repeats no more herein.
The present embodiment passes through the storage medium to process resource occupancy in backup storage cluster lower than the second preset threshold
Quantity be monitored, and in backup storage cluster process resource occupancy lower than the second preset threshold storage medium number
Amount is adjusted the flow rate upper limit between main memory accumulation and backup storage cluster when changing, so that main memory accumulation passes
Defeated data are stored in storage medium more idle in backup storage cluster, thus realizing the same of flow adjust automatically
When, improve processing speed of the data in backup storage cluster.
