> ExternalViewGeneration should be executed asynchronously in Helix controller

> Key: HELIX-706
> URL: https://issues.apache.org/jira/browse/HELIX-706
> Project: Apache Helix
> Issue Type: Task
> Reporter: Hao Zhang
> Priority: Major
>
> EV generation should not block helix resource rebalance. According to our
> profiling results, external view generation takes ~ 1/5 of the pipeline
> latency.
> The goal is to generate external view asynchronously, and hopefully we can
> have 20% improvement in rebalance pipeline
