[jira] [Updated] (HBASE-24205) Create metric to know the number of
reads that happens from memstore
[ https://issues.apache.org/jira/browse/HBASE-24205?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
ramkrishna.s.vasudevan updated HBASE-24205:
-------------------------------------------
Description:
A metric to identify number of reads that were served from memstore (atleast if the gets can be accounted for) then it gives a value addition to know if among the reads how much was targeted at the most recent data.
Currently the existing metric framework at region level should be enough but we can also add a metric per store level. That will be more granular.
We can also expose this via HbTop.
