Subject [jira] [Commented] (CASSANDRA-13733) nodetool toptables
Date Thu, 27 Jul 2017 01:03:00 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-13733?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16102545#comment-16102545

Chris Lohfink commented on CASSANDRA-13733:
-------------------------------------------

This could be as simple as printing top X tables by looking at their Latency metrics (rate
in particular), that would require no changes just a view of the data. a new jmx operation
could make it a lot faster so it doesnt require N jmx calls (n=number of tables).

> In the same way toppartitions samples the activity on a table, toptables should be able
to report which tables are used the most.
