------------------------------------

             Summary: RingBufferTruck does not release its payload
                 Key: HBASE-10792
                 URL: https://issues.apache.org/jira/browse/HBASE-10792
             Project: HBase
          Issue Type: Bug
          Components: Performance, wal
    Affects Versions: 0.99.0
            Reporter: Nick Dimiduk


Run a write-heavy workload (PerfEval sequentialWrite) out of a trunk sandbox 
and watch as HBase eventually dies with an OOM: heap space. Examining the heap 
dump shows an extremely large retained size of KeyValue and RingBufferTrunk 
instances. By my eye, the default value of 
{{hbase.regionserver.wal.disruptor.event.count}} is too large for such a small 
default heap size, or the RBT instances need to release their payloads after 
consumers retrieve them.
