> BatchConsumer - Allow consumers to be batch aware
> -------------------------------------------------
>
> Key: CAMEL-1640
> URL: https://issues.apache.org/activemq/browse/CAMEL-1640
> Project: Apache Camel
> Issue Type: New Feature
> Components: camel-core
> Affects Versions: 2.0-M1
> Reporter: Claus Ibsen
> Assignee: Claus Ibsen
> Fix For: 2.0.0
>
>
> Most of the consumers can handle batch but they dont decorate the Exchange
> with this information.
> Only the file component does this.
> We should expose a {{BatchConsumer}} interface to mark a consumer as being
> batch capable.
> Then this consumer should be able to round up the exchanges beforehand they
> are processed. This allows us to gather the total number of exchanges in the
> batch.
> And then afterwards loop this list and emit each exchange with information
> about: current index out of total.
> This also makes it much easier to support aggregator afterwards as the
> aggregator will be able to support BatchConsumer and then know when it has
> the complete batch aggregated.
> In camel-core its the *file* component that should be batch aware.
> Other components such as: mail, rss, atom, and many others can support this
> as well.
