Corentin Chary created CASSANDRA-13338: ------------------------------------------
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. cc: [~rgerard] -- This message was sent by Atlassian JIRA (v6.3.15#6346)
