Andrey Gura created IGNITE-2646: ----------------------------------- Summary: 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 Assignee: 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.) Rerated discussion on dev-list: [IgniteCompute.withAsync can execute tasks synchronously|http://apache-ignite-developers.2346864.n4.nabble.com/IgniteCompute-withAsync-can-execute-tasks-synchronously-td7262.html] -- This message was sent by Atlassian JIRA (v6.3.4#6332)
