Hao Zhang created HELIX-709: ------------------------------- Summary: Prepare controller stages for async execution Key: HELIX-709 URL: https://issues.apache.org/jira/browse/HELIX-709 Project: Apache Helix Issue Type: Task Reporter: Hao Zhang
There are a couple of stages in helix controller that can be executed asynchronously, but each execution should be done in order. Currently for helix controller, we have a thread pool for un-ordered execution, but we also need one for ordered execution. In this ticket should do the following: 1. Create a pool of configurable workers using DedupEventProcessor 2. Create AbstractAsyncBaseStage for those stages that can be executed asynchronously to share common code AC: Create AbstractAsyncBaseStage and DedupFIFOWorkerPool for async execution, pass all tests. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
