-------------------------------------
Summary: Use medium priority for UPSERT SELECT distributed across
cluster
Key: PHOENIX-3995
URL: https://issues.apache.org/jira/browse/PHOENIX-3995
Project: Phoenix
Issue Type: Bug
Reporter: James Taylor
Assignee: Samarth Jain
An UPSERT SELECT that is running on the server-side should use a medium
priority (lower than index priority but higher than normal priority) to prevent
deadlocks. If we use the index priority, then there's a danger of deadlocks
occurring if the table being upserted into also as indexes (as the index
updates would be processed at the index priority).
