Description

Some minor optimizations for write path, particularly for small writes use-cases like hbase:

1. Usage Collection.parallelStream() is premature and bring more cost than benefit. The Fork/Join model of parallelStream is just paranoid for small collection processing.
   
2. Remove unnecessary UUID creation in ChunkBufferImplWithByteBuffer.
   
3. Remove a unnecessary lock in KeyOutputStream.
