Hi all, As described in FLINK-15145 [1], we decided to tune the default configuration values of FLIP-49 with more jobs and cases.
After spending time analyzing and tuning the configurations, I've come with several findings. To be brief, I would suggest the following changes, and for more details please take a look at my tuning report [2]. - Change default managed memory fraction from 0.4 to 0.3. - Change default JVM metaspace size from 128MB to 64MB. - Change default JVM overhead min size from 128MB to 196MB. Looking forward to your feedback. Thank you~ Xintong Song [1] https://issues.apache.org/jira/browse/FLINK-15145 [2] https://docs.google.com/document/d/1-LravhQYUIkXb7rh0XnBB78vSvhp3ecLSAgsiabfVkk/edit?usp=sharing
