Hangxiang Yu commented on FLINK-33819: -------------------------------------- merged 4f7725aa into master which is not blocked by the performance result. [~mayuehappy] Thanks for the test! What's the state size and memory configuration in your test ? Could we also test when state is larger than L2/L3 ? I also think it's worthy discussing and we could find a better default behavious in the next version. > Support setting CompressType in RocksDBStateBackend > --------------------------------------------------- > > Key: FLINK-33819 > URL: https://issues.apache.org/jira/browse/FLINK-33819 > Project: Flink > Issue Type: Improvement > Components: Runtime / State Backends > Affects Versions: 1.18.0 > Reporter: Yue Ma > Assignee: Yue Ma > Priority: Major > Labels: pull-request-available > Fix For: 1.19.0 > > Attachments: image-2023-12-14-11-32-32-968.png, > image-2023-12-14-11-35-22-306.png > > > Currently, RocksDBStateBackend does not support setting the compression > level, and Snappy is used for compression by default.
