[jira] [Created] (CASSANDRA-15390) Avoid unnecessary collection/iterator allocations during btree construction

Blake Eggleston created CASSANDRA-15390:
-------------------------------------------

             Summary: Avoid unnecessary collection/iterator allocations during btree construction
                 Key: CASSANDRA-15390
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-15390
             Project: Cassandra
          Issue Type: Sub-task
          Components: Local/Compaction
            Reporter: Blake Eggleston
            Assignee: Blake Eggleston


A heavily used btree builder path does a lot of unnecessary conversions to and from collections and iterators. Adding dedicated support for Object[] reduces compaction garbage by up to 8.3%
