             Summary: OpOrder groups do not clear their next pointer
                 Key: CASSANDRA-21799
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-21799
             Project: Apache Cassandra
          Issue Type: Improvement
          Components: Local/Other
            Reporter: Branimir Lambov
            Assignee: Branimir Lambov


While this is not required for correctness, when the forward links are left in 
place and a group/barrier manages to get promoted to the heap's old generation, 
all barriers after the promoted one also become eligible for promotion and 
cannot be cleared until an old-gen GC cycle.

We have seen this cause significant GC pauses for off-heap trie memtables.
