> -------------------------------------------------------------------------

> Key: IGNITE-1650
> URL: https://issues.apache.org/jira/browse/IGNITE-1650
> Project: Ignite
> Issue Type: Task
> Components: general
> Affects Versions: ignite-1.4
> Reporter: Vladimir Ozerov
> Priority: Critical
> Fix For: 1.6
>
>
> Closures passed to IgniteFuture listen() and chain() methods are executed
> either in the same thread if future is completed, or in a completion thread
> (usually this is a thread from one of Ignite pools).
> This enforces restrictions on what user can do in closures. He cannot use
> call operations, he cannot call any Ignite operations. Otherwise deadlocks or
> starvation could occur.
> To fix that we should allow user to pass optional thread pool where passed
> closure should be executed. This already done in Java 8 CompletableFuture. We
> should do almost the same.
