问题
I have a general question about Apache Camel. I wasn't able to find whether the aggregator is transacted. If it is transacted, how the transactions are implemented and how fast the aggregation is?
回答1:
Sending the messages into the aggregator can run in a transaction.
You would need a persistent store with the aggregator to let the outgoing messages act as a transaction. See the documentation about persistence http://camel.apache.org/aggregator2
For example there is a JDBC based and HawtDB (file based) persistent support out of the box. Its pluggable as you can also build your custom.
Camel in Action book chapter 8 and 9 convers this in much more details.
