Shammon updated FLINK-25329: ---------------------------- Summary: Improvement of execution graph store in flink session cluster for jobs (was: Improvement of disk operations in flink session cluster for jobs) > Improvement of execution graph store 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. -- This message was sent by Atlassian Jira (v8.20.1#820001)
