Competing Consumers

Camel supports the Competing Consumers from the EIP patterns using a few different components.

You can use the following components to implement competing consumers:-

  • Seda for SEDA based concurrent processing using a thread pool
  • JMS for distributed SEDA based concurrent processing with queues which support reliable load balancing, failover and clustering.

Enabling Competing Consumers with JMS

To enable Competing Consumers you just need to set the concurrentConsumers property on the JMS endpoint.

For example

or in Spring DSL

Or just run multiple JVMs of any ActiveMQ or JMS route (smile)

Using This Pattern

If you would like to use this EIP Pattern then please read the Getting Started, you may also find the Architecture useful particularly the description of Endpoint and URIs. Then you could try out some of the Examples first before trying this pattern out.
