Matthias created FLINK-19904:
--------------------------------
Summary: Update documentation to address difference between -Xmx
and the metric for maximum heap
Key: FLINK-19904
URL: https://issues.apache.org/jira/browse/FLINK-19904
Project: Flink
Issue Type: Improvement
Components: Documentation, Runtime / Metrics
Affects Versions: 1.11.2, 1.10.2
Reporter: Matthias
Fix For: 1.12.0
We observed a difference between the configured maximum heap and the maximum
heap returned by the metric system. This is caused by the used garbage
collection (see [this
blogpost|https://plumbr.io/blog/memory-leaks/less-memory-than-xmx] for further
details.
We should make the user aware of this in the documentation mentioning it in the
memory configuration and the metrics page.
