Embodiment 1

[0051] Such as figure 1 As shown, the present invention provides an adaptive current limiting method of data writing rate, which is applied in a distributed storage system, including:

[0052] S1, performing data writing control on multiple IO instances;

[0053] S2, obtaining the data writing request to be written in each IO instance, and analyzing and obtaining the amount of data to be written contained in the data writing request;

[0054] S3, according to the amount of data to be written, judge the amount of data that can be written in the current first cycle for comparison, and judge whether the amount of data that can be written in the current first cycle is not less than the amount of data to be written, if the judgment result is If yes, execute step S4; if the judgment result is no, execute step S5;

[0055] S4, controlling the writing of data to be written, and updating the amount of data that can be written in the current first cycle;

[0056] S5, put the data wri...

Embodiment 2

[0096] Such as Figure 5 As shown, the technical solution of the present invention also provides an adaptive current limiting device for data writing rate, which is applied to a distributed storage system, including:

[0097] The control module 101 performs data writing control on multiple IO instances;

[0098] Obtaining the parsing module 102, obtaining the data writing request to be written in each IO instance, and analyzing and obtaining the amount of data to be written contained in the data writing request;

[0099] Comparing module 103 judges the amount of data that can be written in the current first cycle according to the amount of data to be written for comparison, if the amount of data that can be written in the current first cycle is not less than the amount of data to be written, control the amount of data to be written Write the incoming data, and update the amount of data that can be written in the current first cycle; if the amount of data that can be written i...

Embodiment 3

[0133] Such as Figure 7 As shown, the technical solution of the present invention also provides an electronic device, including: a memory 201 for storing a computer program; a processor 202 for implementing the data writing rate as described in Embodiment 1 when executing the computer program The steps of the adaptive current limiting method.

Abstract

The invention provides a self-adaptive flow limiting method for a data writing rate, which is applied to a distributed storage system and comprises the following steps: performing data writing control on a plurality of IO instances; obtaining a to-be-written data writing request in each IO instance; according to the to-be-written data volume, judging and comparing the data volume which can be written in the current first period, if the data volume which can be written in the current first period is not smaller than the to-be-written data volume, controlling the to-be-written data to be written in, and updating the data volume which can be written in the current first period; and if yes, carrying out data writing rate self-adaptive adjustment according to the number of the first periods waiting for the data writing request in the second period, and setting the writable data volume in the current first period according to the adjusted data writing rate. The invention further provides a self-adaptive flow limiting device and equipment for the data writing rate and a medium, and the reliability of limiting the data writing rate is effectively improved.

Description

technical field [0001] The present invention relates to the field of distributed storage systems, in particular to an adaptive current limiting method, device, equipment and medium for data writing rate. Background technique [0002] In the field of distributed storage, under special circumstances, we need to consider controlling the write rate of internal data operations in the system, such as cache flushing, log merging, etc. , due to the performance bottleneck of the hard disk, it will increase the data reading delay, affect the reading performance, and then affect the front-end business. Some data writing operations inside the distributed storage system will compete with user services if rate control is not performed, affecting front-end user services. [0003] The current rate limiting method, one is to limit the number of requests per unit time through a counter, but this method is not easy to determine whether the IO (Input / Output, input / output) operation size of a s...
