Column family and metrics cause a very high object (and name) cound in mbean server. #135

Open elcallio opened 4 years ago

For every CF, we bind some 50+ metrics, each under two different names (Table and ColumnFamily). This leads to rather high object counts if the associated server has many CF:s.

Since objects are also only reaped when a wildcard query is issued, it is somewhat possible to cause objects to remain bound that represent dropped CF:s for quite some time, depending on query pattern or JMX commands run.
