…ange tombstone markers ClusteringPrefix.Kind.values() creates a new array on every call. This happens when Cassandra deserializes range tombstone markers. I found this while using Temporal with Cassandra. Temporal uses many range deletes. In this workload, this array allocation was about 3% of the total memory allocations. This code also used noticeable CPU time. Cache the values array to avoid this repeated work. Thanks. :) patch by koo.taejin for CASSANDRA-21528 The [Cassandra Jira](https://issues.apache.org/jira/browse/CASSANDRA-21528) -- This is an automated message from the Apache Git Service.
