Seda concurrent consumers with aggregator

Is it valid to concurrently process messages into an aggregator?
There is no mention of "aggregator" in Camel docs for parallel processing,
want to be sure.


<route id="aggregatorRoute">
      <from uri="seda:workBasket?concurrentConsumers=5" />
      <aggregate strategyRef="objectAggregator" completionSize="50">
        <correlationExpression>
          <constant>true</constant>
        </correlationExpression>
        <to uri="jpa:?entityType=java.util.ArrayList" />
      </aggregate>
    </route>

Hi

That will only concurrently send in messages into the aggregator. The
aggregation happens single threaded by default (unless you turn on
optimisticLocking).

You can turn on parallel processing on the aggragator so outgouing
messages can be processed concurrently. There is options to configure
the pool size and refer to thread pools and whatnot.
