------------------------------------------
Summary: Resolve Compute futures on node stop that had no chance
to be executed
Key: IGNITE-16705
URL: https://issues.apache.org/jira/browse/IGNITE-16705
Project: Ignite
Issue Type: Improvement
Components: compute
Reporter: Roman Puchkovskiy
Assignee: Roman Puchkovskiy
Fix For: 3.0.0-alpha5
We execute Compute jobs using a separate ExecutorService. It has a bounded
number of threads and an unbounded work queue. It might happen that on node
stop some tasks are not executed, so their corresponding futures never get
resolved.
The standard CompletableFuture does not provide any built-in mechanisms for
solving this problem.
We should track the futures ourselves and cancel the unresolved ones after
stopping the executor.
