----------------------------------------
Summary: Document stability concerns of flamegraphs for heavier
jobs
Key: FLINK-22235
URL: https://issues.apache.org/jira/browse/FLINK-22235
Project: Flink
Issue Type: Improvement
Components: Documentation, Runtime / Web Frontend
Reporter: Chesnay Schepler
Fix For: 1.13.0
The FlameGraph feature added in FLINK-13550 has some known scalability issues,
because it issues 1 RPC call per subtask. This may put a lot of pressure on the
RPC system, and as such it should be used with caution for heavier jobs until
we improved this a bit.
