-------------------------------------
Summary: Determine the usefulness of tracing
Key: PHOENIX-1519
URL: https://issues.apache.org/jira/browse/PHOENIX-1519
Project: Phoenix
Issue Type: Sub-task
Reporter: James Taylor
In order to help prioritize the child JIRAs under PHOENIX-1121, we need to do a
usability study around tracing. What problem(s) are we trying to solve and
what's the delta between the existing tracing feature and the required tracing
features.
For example, is the main use case of tracing to determine the top 10 queries
that take the longest amount of time in production? Would we then want tracing
on all the time, so having a way to enable/disable tracing (PHOENIX-1433,
PHOENIX-1191, PHOENIX-1518, PHOENIX-1115) becomes moot.
Or is it more of something that would be used in a perf testing environment
where we'd need to information generated to be only for a particular query (in
which case the above JIRAs are more important)?
