-----------------------------------------
Summary: Add metrics for time taken during mutation plan creation
and execution
Key: PHOENIX-7485
URL: https://issues.apache.org/jira/browse/PHOENIX-7485
Project: Phoenix
Issue Type: Improvement
Reporter: Sanjeet Malhotra
While debugging PHOENIX-7484, it was observed that within an `executeUpdate()`
call we do two major operations i.e. mutation plan creation and execution but
we don't track time taken by each of these operations. Due to not having
visibility we can miss out of some regression getting introduced in this area.
The proposal is to add metrics to track time taken by mutation plan creation
and execution separately.
The time taken by these two phases for a single call to executeUpdate is of the
order of micro seconds and thus, we need to track either at micro second
granularity or nano seconds granularity.
