WSO2 - Execute parallel steps in a sequence like clone mediator

In our project using WSO2 ESB(EI 6.1.0) we have some scenarios where we need to have to execute 2 tasks in parallel.

For example, we have a step for inserting steps of the execution in an audit table, and then proceed to the next steps.

For doing that, we use a clone mediator with a continueParent=true and inside the clone we have the sequence that inserts the audita data inside the db. As we set the continueParent=true, the next step doesn't wait the audit insertion to execute.

This is working fine, but in a high load test, we found that the heap is growing very large.

And checking the heap I see a lot of the instances of the clone mediator, and as it clones the context, it is growing a lot and causing OutOfMemory.

My question is:

Is there a way to have a similar behavior but not using the clone mediator?

Thanks,

If you need to execute asynchronous operations like inserting data in an audit table, you should consider the use of JMS queues in your primary mediation : only send those data in such queues and define a dedicated proxy service or jms inbound endpoint that will consume those messages and insert the data in your table
