[jira] [Created] (PHOENIX-5120) Avoid using MappedByteBuffers for server side sorting.

Lars Hofhansl created PHOENIX-5120:
--------------------------------------

             Summary: Avoid using MappedByteBuffers for server side sorting.
                 Key: PHOENIX-5120
                 URL: https://issues.apache.org/jira/browse/PHOENIX-5120
             Project: Phoenix
          Issue Type: Task
            Reporter: Lars Hofhansl


We should had a production outage due to this.
MappedByteBuffer may leave files around, on top they use direct memory, which is not cleared until the JVM executes a full GC.

See last comment on PHOENIX-2405.
