[jira] [Commented] (HBASE-8402) ScanMetrics depends on number of rpc calls to the server.

    [ https://issues.apache.org/jira/browse/HBASE-8402?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13674083#comment-13674083 ] 

Himanshu Vashishtha commented on HBASE-8402:
--------------------------------------------

With this patch, I could see scan metrics on a small table independent of number of rpc calls (on a local table with 10 rows, I created a scan with cache value of 1, 5, 100). Please review.

> Currently, scan metrics is not published in case there is one trip to server. I was testing it on a small row range (200 rows) with a large cache value (1000). It doesn't look right as metrics should not depend on number of rpc calls (number of rpc call is just one metrics fwiw).
