Optimize Counter, Meter and Histogram metrics using thread local counters Codahale metrics do not provide the ability to create custom metric implementations, so we have to inherit from Codahale classes. For better cache locality rate and counter values are extracted to a common thread-local arrays. Threads death is tracked using 2 approaches: FastThreadLocal.onRemoval callback and phantom references to Thread objects. Phantom references are used to track aliveness of metric users and reusing of metric IDs.
