> While Buffer class is used in multithreaded context it requires synchronisation. Now it is miss-leading/unclear and suggesting that RecordSerializer should take into account synchronisation of the Buffer that's holding. With NotThreadSafe BufferBuilder there would be clear separation between single-threaded writing/creating a BufferBuilder and multithreaded Buffer handling/retaining/recycling.
