Caleb Rackliffe commented on CASSANDRA-14888:
---------------------------------------------
[~stillalex] I think there's a [minor
typo|https://github.com/apache/cassandra/compare/trunk...stillalex:CASSANDRA-14888#diff-8f3132f0fa1e03f77fd29bc9b8163fe3R65]
in {{KeyspaceMetricsTest#testMetricsCleanupOnDrop()}}, but otherwise things
look good so far. (One other minor nit...you probably don't need the JavaDoc
comment for {{ReleasableMetric#release()}}, unless there's something more
substantial we need to say there.)
