-----------------------------------------
Summary: Allow disabling hotness persistence, or tuning of rate
limiter
Key: CASSANDRA-17868
URL: https://issues.apache.org/jira/browse/CASSANDRA-17868
Project: Cassandra
Issue Type: Improvement
Components: Feature/Rate Limiting
Reporter: Josh McKenzie
Assignee: Josh McKenzie
The persisting of the sstables hotness when there are 10s of thousands of
sstables can have issues keeping up, and the rate limiter is hard coded.
Another option may be nice to just completely disable the feature.
When sstables super backed up (from repairs) the hotness tracking tends to
cause the STCS in L0 to make poor decisions, always grabbing the large sstables
and skipping the tiny sstables that would benefit more.
