--------------------------------------------
Summary: Contain explain diagnostic recording
Key: PHOENIX-7967
URL: https://issues.apache.org/jira/browse/PHOENIX-7967
Project: Phoenix
Issue Type: Sub-task
Affects Versions: PHOENIX-7876-feature
Reporter: Andrew Kyle Purtell
Assignee: Andrew Kyle Purtell
Detailed breadcrumb collection should be enabled only when the statement being
compiled is an EXPLAIN. Non-EXPLAIN debug/query loggers and opt-in
CONNECTION_EXPLAIN_PLAN_LOGGING_ENABLED will keep producing plan debug output,
but with thinner labels (no index-rejection reasons, no origin tags, no
functional-match line).
This is a deliberate performance cost reduction for the normal query execution
flow that trades off some diagnostic capability in DEBUG logging. (Note that
before this feature that diagnostic capability did not exist anyway.)
