-------------------------------------
Summary: Flink Restart Strategy does not work as documented
Key: FLINK-35288
URL: https://issues.apache.org/jira/browse/FLINK-35288
Project: Flink
Issue Type: Bug
Reporter: Keshav Kansal
As per the documentation when using the Fixed Delay Restart Strategy, the
restart-strategy.fixed-delay.attempts defines the "The number of times that
Flink retries the execution before the job is declared as failed if has been
set to fixed-delay".
However in reality it is the *maximum-total-task-failures*, i.e. it is possbile
that the job does not even attempt to restart.
This is as per documented in
https://cwiki.apache.org/confluence/display/FLINK/FLIP-1%3A+Fine+Grained+Recovery+from+Task+Failures
If there is an outage at a Sink level, for example Elasticsearch outage, all
the independent tasks might fail and the job will immediately fail without
restart if restart-strategy.fixed-delay.attempts is set lower or equal to the
parallelism of the sink.
