C. Scott Andreas updated CASSANDRA-7022: ---------------------------------------- Component/s: Observability > Consider an option to reduce tracing cost by writing only to sessions table > (not events) > ---------------------------------------------------------------------------------------- > > Key: CASSANDRA-7022 > URL: https://issues.apache.org/jira/browse/CASSANDRA-7022 > Project: Cassandra > Issue Type: Improvement > Components: Observability > Environment: C* 2.0.6 running on Ubuntu 12.04 > Reporter: Bill Joyce > Priority: Minor > > With MySQL and SQL Server, I can profile all queries in high traffic > production environments. I'm assuming the bulk of the C* tracing cost comes > in writing to the system_traces.events table, so it would be great to have an > option to write just the system_traces.session info if that allows me to run > 'nodetool settraceprobability' with a higher probability (ideally a > probability of 1). This along with CASSANDRA-7021 would go a long way in > giving us performance analysis closer to what can be done with more mature > back ends. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: commits-unsubscr...@cassandra.apache.org For additional commands, e-mail: commits-h...@cassandra.apache.org
