Configuration options

Optional configuration options

key	type	default value	description
`backoff-ratio`	double	`0.9`	Backoff ratio to use for the algorithm. The value must be within [0.5, 1.0).
`enable-metrics`	boolean	`false`	Whether to collect metrics for the AIMD implementation.
`fair`	boolean	`false`	Whether the java.util.concurrent.Semaphore should be java.util.concurrent.Semaphore.isFair(). Defaults to `false`.
`initial-limit`	int	`20`	Initial limit. The value must be within [minLimit(), maxLimit()].
`max-limit`	int	`200`	Maximal limit. The value must be same or higher than minLimit().
`min-limit`	int	`20`	Minimal limit. The value must be same or lower than maxLimit().
`queue-length`	int	`0`	How many requests can be enqueued waiting for a permit after the max limit is reached. Note that this may not be an exact behavior due to concurrent invocations. We use java.util.concurrent.Semaphore.getQueueLength() in the io.helidon.common.concurrency.limits.AimdLimit implementation. Default value is `0`. If set to {code 0}, there is no queueing.
`queue-timeout`	Duration	`PT1S`	How long to wait for a permit when enqueued. Defaults to `PT1S`
`timeout`	Duration	`PT5S`	Timeout that when exceeded is the same as if the task failed.
