[jira] [Created] (CASSANDRA-15394) Remove list iterators

Blake Eggleston created CASSANDRA-15394:
-------------------------------------------

             Summary: Remove list iterators
                 Key: CASSANDRA-15394
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-15394
             Project: Cassandra
          Issue Type: Sub-task
          Components: Local/Compaction
            Reporter: Blake Eggleston
            Assignee: Blake Eggleston


We allocate list iterators in several places in hot paths. This converts them to get by index. This provides a ~4% improvement in relvant workloads.
