------------------------------------
Summary: Capture time spent in various stages of exceuteQuery call
Key: PHOENIX-7535
URL: https://issues.apache.org/jira/browse/PHOENIX-7535
Project: Phoenix
Issue Type: Improvement
Reporter: Rahul Kumar
Assignee: Rahul Kumar
Capture time spent in various stages in executeQuery call and expose as
metrics. Stages are:
- Query plan creation.
- Query optimizer
- Creating ResultSetItr object (+ ResultSet object)
Instead of overall query time, capturing stage level detail helps us understand
where majority of time is going in executeQuery where we can further look for
optimisation
