David Capwell updated CASSANDRA-15589: -------------------------------------- Change Category: Operability Complexity: Normal Status: Open (was: Triage Needed) > Add histogram to prepared statements and expose as virtual table > ----------------------------------------------------------------- > > Key: CASSANDRA-15589 > URL: https://issues.apache.org/jira/browse/CASSANDRA-15589 > Project: Cassandra > Issue Type: Improvement > Components: Observability/Metrics > Reporter: Jon Haddad > Priority: Normal > > One of the biggest challenges as an operator is understanding what queries > are being executed and how long they take. We have the ability to take short > samples via profileload, but it’s lacking the full diagnostics that keeping > histograms on each prepared statement could give us. Having this would be a > massive benefit to most operators as they currently have no idea what > Cassandra is actually doing. > Before committing let’s be sure to record some CPU flame graphs to ensure > there isn’t noticeable performance overhead. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: commits-unsubscr...@cassandra.apache.org For additional commands, e-mail: commits-h...@cassandra.apache.org
