Da Huo created FLINK-36343:
------------------------------
Summary: The description on max-parallelism is misleading and
needs to be more specific
Key: FLINK-36343
URL: https://issues.apache.org/jira/browse/FLINK-36343
Project: Flink
Issue Type: Bug
Components: Documentation
Affects Versions: 1.20.0
Reporter: Da Huo
In the yellow box under [the description for
max-parallelism|https://nightlies.apache.org/flink/flink-docs-release-1.20/docs/dev/datastream/execution/parallel/#setting-the-maximum-parallelism],
it mentions setting max-parallelism too high can be detrimental to performance
for some state backends, but it doesn't mention which state backends are
affected.
Had a discussion with [~danderson] , it seems like this only affects hashmap
state backend and does not affect rocksdb state backend. We should clarify this
in the doc.
