T Jake Luciani updated CASSANDRA-7128:
--------------------------------------
Description: Upgrade NBHM to use the Boundary maintained version (was:
AbstractRowResolver uses a NBHM for each read request.
Profiler flagged this as a bottleneck since the init() call creates a
AtomicReferenceFieldUpdater which is stored in a synchronized collection.
A NBHS is most certainly overkill for such a short lived object. And turns out
switching it to a CHS in my tests yields a ~5-10% read boost.)
