Till Rohrmann created FLINK-23209:
-------------------------------------
Summary: Timeout heartbeat if the heartbeat target is no longer
reachable
Key: FLINK-23209
URL: https://issues.apache.org/jira/browse/FLINK-23209
Project: Flink
Issue Type: Improvement
Components: Runtime / Coordination
Affects Versions: 1.12.4, 1.13.1
Reporter: Till Rohrmann
Fix For: 1.14.0, 1.12.5, 1.13.2
With FLINK-23202 it should now be possible to see when a remote RPC endpoint is
no longer reachable. This can be used by the {{HeartbeatManager}} to mark an
heartbeat target as no longer reachable. That way, it is possible for Flink to
react faster to losses of components w/o having to wait for the heartbeat
timeout to expire. This will result in faster recoveries (e.g. if a
{{TaskExecutor}} dies).
