Paulo Motta updated CASSANDRA-13338:
------------------------------------
Complexity: Low Hanging Fruit
Labels: lhf (was: )
> JMX: EstimatedPartitionCount / SnapshotSize are expensive
> ---------------------------------------------------------
>
> Key: CASSANDRA-13338
> URL: https://issues.apache.org/jira/browse/CASSANDRA-13338
> Project: Cassandra
> Issue Type: Improvement
> Components: Legacy/Observability
> Reporter: Corentin Chary
> Priority: Normal
> Labels: lhf
>
> EstimatedPartitionCount / EstimatedRowCount / SnapshotSize seem particularly
> expensive. For example on our system
> org.apache.cassandra.metrics:type=ColumnFamily,name=SnapshotsSize can take as
> much as half a second.
> All this cumulated means that export stats for all your tables (with
> metrics-graphite or jmx_exporter) is going to take quite some time.
> We should certainly try to find the most expensive end points and see if
> there is a way to cache some of the values.
