[jira] [Updated] (FLINK-34176) Remove unnecessary failure-rate and fixed-delay restart-strategies
[ https://issues.apache.org/jira/browse/FLINK-34176?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Rui Fan updated FLINK-34176:
----------------------------
Summary: Remove unnecessary failure-rate and fixed-delay restart-strategies (was: Remove unnecessary implemetations of RestartBackoffTimeStrategy)
> Remove unnecessary failure-rate and fixed-delay restart-strategies

> h2. Could we deprecate the failure-rate and fixed-delay restart-strategies directly?
> After FLINK-33735 (FLIP-364), the exponential-delay restart strategy is already very feature-rich. It can replace fix-delay and failure rate restart strategies directly.
> h2. How to replace fix-delay restart strategy?
> * Set backoffMultiplier = 1 and jitterFactor = 0
> * resetBackoffThresholdMS = Interget.Max
> * initialBackoffMS and maxBackoffMS are the backoffTimeMS of FixedDelayRestartBackoffTimeStrategy
> * attemptsBeforeResetBackoff is the maxNumberRestartAttempts of FixedDelayRestartBackoffTimeStrategy
> h2. How to replace failure-rate restart strategy?
> * Set backoffMultiplier = 1 and jitterFactor = 0
> * resetBackoffThresholdMS is the failuresIntervalMS of FailureRateRestartBackoffTimeStrategy
> * initialBackoffMS and maxBackoffMS are the backoffTimeMS of FailureRateRestartBackoffTimeStrategy
> * attemptsBeforeResetBackoff is the maxFailuresPerInterval of FailureRateRestartBackoffTimeStrategy
