Batch Consumer
Since Camel 2.0
Batch Consumer is basically a Polling
Consumer that is capable of polling multiple
Exchanges in a pool. What we have done in Camel 2.0
is to standardize this into a org.apache.camel.BatchConsumer interface
that a consumer can implement to indicate it support batching as well.
The following components supports Batch Consumer by its consumer:
