Summary: Remove string formatting lines from hot path
Key: CASSANDRA-14416
URL: https://issues.apache.org/jira/browse/CASSANDRA-14416
Project: Cassandra
Issue Type: Improvement
Components: Core
Reporter: Jeff Jirsa
Assignee: Jeff Jirsa
Fix For: 3.11.x, 4.x
In the BufferPool, we have a {{NoSpamLogger}} that gets called in some
conditions (like when we're at or near the cap in a given pool), which has some
string formatting on it. In situations where that log line is invoked, that
string formatting gets called before the rate limiting, which becomes
expensive.
