[jira] [Created] (CASSANDRA-9579) Add JMX / nodetool command to refresh system.size_estimates

---------------------------------------------

             Summary: Add JMX / nodetool command to refresh system.size_estimates
                 Key: CASSANDRA-9579
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-9579
             Project: Cassandra
          Issue Type: Improvement
          Components: API
            Reporter: Piotr Kołaczkowski
            Priority: Minor


CASSANDRA-7688 added dumping size estimates at a fixed interval. However, in some cases, e.g. after inserting huge amounts of data or truncating a table, size estimates may become severely incorrect for the interval time. In this case being able to manually trigger the recalculation of the estimates would be very useful. It would be also useful for any automated testing requiring fresh size estimates.
