-----------------------------------------
Summary: Add metrics to capture HTable thread pool utilization and
contention
Key: PHOENIX-7626
URL: https://issues.apache.org/jira/browse/PHOENIX-7626
Project: Phoenix
Issue Type: Improvement
Affects Versions: 5.3
Reporter: Sanjeet Malhotra
Assignee: Sanjeet Malhotra
PHOENIX-7605 added ability to configure per CQSI HTable thread pool. With this
change, someone can either use separate HTable thread pools per CQSI instance
or can specify external HTable thread pool by possibly providing an
implementation of HTableFactory. (Above two options are in addition to HBase
client itself managing the HTable thread pool.) In either of the cases we
currently don't have a way to capture utilization/contention at the HTable
thread pool level. This Jira aims to add metrics and a framework in general
which can be used for CQSI based HTable thread pool and external HTable thread
pool both to get visibility on utilization and contention being observed at
HTable thread pool level.
