Shammon updated FLINK-25329:
----------------------------
Parent: FLINK-25318
Issue Type: Sub-task (was: Improvement)
> Improvement of disk operations in flink session cluster for jobs
> ----------------------------------------------------------------
>
> Key: FLINK-25329
> URL: https://issues.apache.org/jira/browse/FLINK-25329
> Project: Flink
> Issue Type: Sub-task
> Components: Runtime / Coordination
> Affects Versions: 1.14.0, 1.12.5, 1.13.3
> Reporter: Shammon
> Priority: Major
>
> Flink session cluster uses files to store info of jobs after they reach
> termination with `FileExecutionGraphInfoStore`, each job will generate one
> file. When the cluster executes many small jobs concurrently, there will be
> many disk related operations, which will
> 1> Increase the CPU usage of `Dispatcher`
> 2> Decrease the performance of the jobs in the cluster.
> We hope to improve the disk operations in `FileExecutionGraphInfoStore` to
> increase the performance of session cluster.
