public class ThreadsProcessor extends org.apache.camel.support.AsyncProcessorSupport implements org.apache.camel.spi.IdAware, org.apache.camel.spi.RouteIdAware
Threads processor that leverage a thread pool for continue processing the Exchanges using the asynchronous routing engine.

Notice: For transacted routes then this ThreadsProcessor is not in use, as we want to process messages using the same thread to support all work done in the same transaction. The reason is that the transaction manager that orchestrate the transaction, requires all the work to be done on the same thread.

Pay attention to how this processor handles rejected tasks.

  • Abort - The current exchange will be set with a RejectedExecutionException exception, and marked to stop continue routing. The UnitOfWork will be regarded as failed, due the exception.
  • CallerRuns - The current exchange will be processed by the current thread. Which mean the current thread will not be free to process a new exchange, as its processing the current exchange.
