io.helidon.faulttolerance.Retry.JitterRetryPolicy
- All Implemented Interfaces:
Retry.RetryPolicy
- Enclosing interface:
Retry
A retry policy that randomizes delays between execution using a "jitter" time.
Consider the following setup:
calls = 4
delayMillis = 100
jitter = 50
- Initial call - always immediate (not handled by retry policy)
- First retry: 50 - 150 millis (delay +- Random.nextInt(jitter)
- Second retry: 50 - 150 millis
- Third retry: 50 - 150 millis

builder
A new fluent API builder to configure instances ofRetry
.- Returns:
- a new builder
-
nextDelayMillis
Description copied from interface:Retry.RetryPolicy
Return next delay in milliseconds, or an empty optional to finish retries.- Specified by:
nextDelayMillis
in interfaceRetry.RetryPolicy
- Parameters:
firstCallNanos
- milliseconds recorded before the first call usingSystem.currentTimeMillis()
lastDelay
- last delay that was used (0 for the first failed call)call
- call index (0 for the first failed call)- Returns:
- how long to wait before trying again, or empty to notify this is the end of retries
