> 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
