-------------------------------------
Summary: Only record trace if query exceeds latency threshold.
Key: CASSANDRA-8380
URL: https://issues.apache.org/jira/browse/CASSANDRA-8380
Project: Cassandra
Issue Type: Improvement
Reporter: Matt Stump
Priority: Critical
Probabilistic trace isn't very useful because you're typically trying to only
find the badly performing queries which may only be .01% of requests. I would
like to enable probabilistic trace on a sample of queries, but then only record
the trace if the request exceeded a time threshold. This would allow us to more
easily isolate performance problems.
