      Description

      With some minor adjustments, the Java IPC stream reader could be more friendly to allow for low level message processing. By that I mean reading a stream and examining messages without necessarily having to load the Record Batch data. These include

      • Separate MessageChannelReader.readNextMessage to allow access to the buffer containing the message.
      • MessageChannelReader input channel should be protected
      • ArrowStreamWriter should make the message to end a stream static
      • WriteChannel intToBytes could write to existing bytes or byte buffer instead of creating new array
