> URL: https://issues.apache.org/jira/browse/ZOOKEEPER-2736
> Project: ZooKeeper

> Components: server
> Affects Versions: 3.4.9, 3.5.2
> Reporter: Vincent Poon
> Attachments: ZOOKEEPER-2736.v1.patch
>
>
> Currently the maxClientCnxns property only limits the aggregate number of
> connections from a client, but not the rate at which connections can be
> created.
> This patch adds a configurable connection rate limiter which limits the rate
> as well.
