-----------------------------------------
Summary: Cassandra should provide a parameter to completely
disable metrics-core
Key: CASSANDRA-13854
URL: https://issues.apache.org/jira/browse/CASSANDRA-13854
Project: Cassandra
Issue Type: Improvement
Components: Metrics
Reporter: Yangzheng Bai
Priority: Minor
We found that Java metrics-core contributes 10%~15% performance impact on some
aarch64 systems. Because metrics update is heavily rely on atomic instructions
and the cost of atomic instruction is one of the bottlenecks which prevents
Cassandra scaling up to 64 or more cores.
Because Java metrics-core is only for diagnostic purpose, we suggest there
should be a parameter in cassandra.yaml to completely disable it.
