>
> It would be nice to see Beam using custom ByteArrayInput/OutputStream without
> synchronization. It currently uses `ThreadLocal`, so using thread-safe stream
> seems unnecessary. And all streams should never be access by more than 1
> thread from the start anyway.
> Simply getting rid of the synchronized keyword will speed up about ~500 times
> for single byte access. Something like org.apache.beam.sdk.util.VarInt will
> get significant benefit from it.
