[jira] [Created] (RATIS-1176) Benchmark various ways to stream data

Tsz-wo Sze created RATIS-1176:
---------------------------------

             Summary: Benchmark various ways to stream data
                 Key: RATIS-1176
                 URL: https://issues.apache.org/jira/browse/RATIS-1176
             Project: Ratis
          Issue Type: Sub-task
          Components: client, Streaming
            Reporter: Tsz-wo Sze


In RATIS-1175, we provided a WritableByteChannel view of DataStreamOutput in order to support FileChannel.transferTo.  However, [~runzhiwang] pointed out that sun.nio.ch.FileChannelImpl.transferTo has three submethods
# transferToDirectly (fastest)
# transferToTrustedChannel
# transferToArbitraryChannel (slowest, requires buffer copying)
Unfortunately, our current implementation only able to use transferToArbitraryChannel.
