### camel-zookeeper-master

The https://github.com/apache/camel/blob/camel-{camel-version}/components/camel-zookeeper-master/src/main/docs/zookeeper-master-component.adoc[zookeeper-master,window=_blank] component provides a way to ensure only a single consumer in a cluster consumes from a given endpoint; with automatic failover if that JVM dies.

This can be very useful if you need to consume from some legacy back end which either doesn’t support concurrent consumption or due to commercial or stability reasons you can only have a single connection at any point in time.
