> Add property to disable server merges for hinted uncovered indexes
> ------------------------------------------------------------------
>
> Key: PHOENIX-6986
> URL: https://issues.apache.org/jira/browse/PHOENIX-6986
> Project: Phoenix
> Issue Type: Improvement
> Components: core
> Reporter: Istvan Toth
> Assignee: Abhishek Kothalikar
> Priority: Major
> Fix For: 5.2.0, 5.1.4
>
>
> The new server merge query plan can perform worse than the old skip-join-scan
> plan.
> Add a property to completely disable it.
> This should help with migrating workloads to the new version, without having
> to verify if server merge performs well, and having add hints to disable it
> where needed.
