> IgniteCompute.withAsync can execute tasks synchronously
> -------------------------------------------------------
>
> Key: IGNITE-2646
> URL: https://issues.apache.org/jira/browse/IGNITE-2646
> Project: Ignite
> Issue Type: Bug
> Components: compute
> Affects Versions: 1.5.0.final
> Reporter: Andrey Gura
>
> {{GridTaskWorker}} can invoke {{reduce}} method in caller thread.
> If task isn't annotated by {{@ComputeTaskMapAsync}} then job mapping will be
> run in caller thread. Since job mapping will be finished
> {{processDelayedResponses}} method will be invoked and if delayed responses
> queue isn't empty then caller thread can invoke {{reduce}} method eventually
> and perform reducing synchronously.
> It can be usefull in case of synchronous execution but it is strange behavior
> for asynchronous case because user expects that method will return after
> creation of task.
> Similar behavior is possible for all places where code invokes
> {{GridTaskProcessor.execute()}} method ({{IgniteCompute.broadcast()}},
> {{IgniteCache.size()}}, REST handlers, etc.)
