--------------------------------------

             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.
