Hello Jan! It seems that if you need to release the whole sequence once it is completed, and handle different sequences at the same time, one of the obvious choices would be using Aggregate EIP <https://camel.apache.org/components/4.4.x/eips/aggregate-eip.html> and set up the following properties: - correlationExpression: It will identify which group of messages the current message belongs to. - completionPredicate or AggregationStrategy object implementing Predicate: it will identify when a batch of messages should be released. - aggregationStrategy: object that will build the resulting aggregate message by merging messages into one message in the right order or handling the case of absence of some messages from a group. - completionTimeoutExpression: it will specify your timeout, after which an incomplete batch can be sent to aggregationStrategy for handling.
While Resequence EIP can also be used for this, you will need to have some correlation and merging logic in your camel routes after resequencing to assemble messages from different sequences. So, I think in your case Aggregate EIP suits better, because the only thing Resequence EIP does is, well, changing sequence of messages, but apart from resequencing you also need correlation and merging of your messages.
