Bill Joyce created CASSANDRA-7022: ------------------------------------- Summary: 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: Core 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 (v6.2#6252)
