------------------------------------------
Summary: JMX: EstimatedPartitionCount / SnapshotSize are expensive
Key: CASSANDRA-13338
URL: https://issues.apache.org/jira/browse/CASSANDRA-13338
Project: Cassandra
Issue Type: Improvement
Components: Observability
Reporter: Corentin Chary
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.
