------------------------------------
Summary: Expose max refCount among all compacted store files of a
region
Key: HBASE-23349
URL: https://issues.apache.org/jira/browse/HBASE-23349
Project: HBase
Issue Type: Task
Affects Versions: 3.0.0, 2.3.0, 1.6.0
Reporter: Viraj Jasani
Assignee: Viraj Jasani
We should expose a region level metric that represents max refCount among
refCounts of all compacted store files under the region. For successful
archival of compacted store files, it is important for this metric count to be
0 eventually if not immediately. If it is >0 for a considerably high amount of
time, it indicates some issue i.e. reader refCount leak on some compacted store
files and in such case, archival would not be successful.
