[jira] [Created] (IGNITE-16747) Avoid user tasks in following future stages blocking system threads

Roman Puchkovskiy created IGNITE-16747:
------------------------------------------

             Summary: Avoid user tasks in following future stages blocking system threads
                 Key: IGNITE-16747
                 URL: https://issues.apache.org/jira/browse/IGNITE-16747
             Project: Ignite
          Issue Type: Improvement
          Components: compute
            Reporter: Roman Puchkovskiy
            Assignee: Roman Puchkovskiy
             Fix For: 3.0.0-alpha5


User job is executed in a dedicated thread pool. We return a CompletableFuture to which the user may add more stages. These stages could still be executed in the same Compute dedicated thread pool, so if a follow-up stages of the returned future run some heavy tasks, they can potentially block the job execution thread pool which may be a problem.
