Rui Fan updated FLINK-32895:
----------------------------
Description:
Currently, Flink has 3 restart strategies, they are: fixed-delay, failure-rate
and exponential-delay.
The exponential-delay is suitable if a job continues to fail for a period of
time. The fixed-delay and failure-rate has the max attempts mechanism, that
means, the job won't restart and go to fail after the attempt exceeds the
threshold of max attemepts.
The max attempts mechanism is reasonable, flink should not or need to
infinitely restart the job if the job keeps failing. However, the
exponential-delay doesn't have the max attempts mechanism.
I propose inctroducing the
`restart-strategy.exponential-delay.max-attempts-before-reset` to support the
max attempts mechanism for exponential-delay. It means flink won't restart job
if the number of job failures before reset exceeds max-attempts-before-reset
when is exponential-delay is enabled.
