[jira] [Created] (FLINK-34176) Remove unnecessary implemetations of RestartBackoffTimeStrategy

Rui Fan created FLINK-34176:
-------------------------------

             Summary: Remove unnecessary implemetations of RestartBackoffTimeStrategy
                 Key: FLINK-34176
                 URL: https://issues.apache.org/jira/browse/FLINK-34176
             Project: Flink
          Issue Type: Improvement
          Components: Runtime / Coordination
            Reporter: Rui Fan
            Assignee: Rui Fan


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 FixedDelayRestartBackoffTimeStrategy?
 * 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 FailureRateRestartBackoffTimeStrategy?
 * 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
