-------------------------------------
Summary: Throttle distributed UPSERT SELECT as necessary
Key: PHOENIX-3737
URL: https://issues.apache.org/jira/browse/PHOENIX-3737
Project: Phoenix
Issue Type: Improvement
Reporter: James Taylor
We run UPSERT SELECT in a distributed manner when possible (see PHOENIX-3271).
If we're upserting into a new table, then the first, initial region will get
hammered by potentially many other RS making cross region calls. If this causes
issues with the region server, we should throttle these calls.
