------------------------------------
Summary: Reduce JVM Metaspace memory for StateFun
Key: FLINK-22751
URL: https://issues.apache.org/jira/browse/FLINK-22751
Project: Flink
Issue Type: Sub-task
Components: Stateful Functions
Reporter: Stephan Ewen
Flink by default reserves quite a lot of metaspace memory (256 MB) out of the
total memory budget, to accommodate applications that load (and reload) a lot
of classes. That is necessary because user code is executed directly in the JVM.
StateFun by default doesn't execute code in the JVM, so it needs much less
Metaspace memory. I would suggest to reduce the Metaspace size to something
like 64MB or 96MB by default.
{{taskmanager.memory.jvm-metaspace.size: 64m}}.
