Throttler
The Throttler Pattern allows you to ensure that a specific endpoint does not get overloaded, or that we don't exceed an agreed SLA with some external service.
Using the Fluent Builders
So the above example will throttle messages all messages received on seda:a before being sent to mock:result ensuring that a maximum of 3 messages are sent in any 30 second window. Note that typically you would often use the default time period of a second. So to throttle requests at 100 requet per second between two endpoints it would look more like this...
from("seda:a").throttler(100).to("seda:b");
For further examples of this pattern in use you could look at the junit test case
Using the Spring XML Extensions
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.
