Description

For the implementation of the off-heap memory store (NEMO-350), I figured out that SerializedPartition should be written by an output stream that utilizes off-heap memory. Currently, it is being written by DirectByteArrayOutputStream which uses on-heap memory with a byte array.

This can be achieved by implementing a customized output stream backed by ByteBuffer, calling it as DirectByteBufferOutputStream, to substitute DirectByteArrayOutputStream.
