Hi, I would require to execute tasks mixing parallel and sequential execution (Barrier synchronization). As an example, we could take the following queue of tasks:
queue: -->(task1)-->(task2, task3, task4)-->(task5)-->(task6,task7) Group of tasks = (task1, …, taskn) Groups of tasks are executed sequentially Tasks in a group are executed in parallel I could achieve this by wrapping each task in a Callable, submitting them to an ExecutorService and implementing the barrier synchronization based on the Future returned by the executor. However, I noticed the sling's ThreadPool [0] is only processing Runnable (no Callable) and thus I am wondering if there is a better way to enable this synchronization in Sling (maybe using event queues). Otherwise, it would be easy to add the Callable support. Regards, Timothee. [0] org.apache.sling.commons.threads.ThreadPool
