Nick Travers commented on ZOOKEEPER-2869:
-----------------------------------------
Ah, good to know [~dbenediktson]!
We're also happy to also offer up a patch on this one, but if you have
something that's been battle-tested, that would be preferable.
> Allow for exponential backoff in ClientCnxn.SendThread on connection
> re-establishment

> Key: ZOOKEEPER-2869
> URL: https://issues.apache.org/jira/browse/ZOOKEEPER-2869
> Project: ZooKeeper
> Issue Type: Improvement
> Components: java client
> Affects Versions: 3.4.10, 3.5.3
> Reporter: Nick Travers
> Priority: Minor
>
> As part of ZOOKEEPER-961, when the client re-establishes a connection to the
> server, it will sleep for a random number of milliseconds in the range [0,
> 1000). Introduced
> [here|https://github.com/apache/zookeeper/commit/d84dc077d576b7cdfbfd003e3425fab85ca29a44].
> These reconnects can cause excessive logging in clients if the server is
> unavailable for an extended period of time, with reconnects every 500ms on
> average.
> One solution could be to allow for exponential backoff in the client. The
> backoff params could be made configurable.
> [3.5.x
> code|https://github.com/apache/zookeeper/blob/release-3.5.3/src/java/main/org/apache/zookeeper/ClientCnxn.java#L1059].
> [3.4.x
> code|https://github.com/apache/zookeeper/blob/release-3.4.9/src/java/main/org/apache/zookeeper/ClientCnxn.java#L1051].
