> Beam Python SDK is couple of magnitude slower than Java SDK when it comes to stream processing.
> There are two related issues:
> # Given a single core, currently we are not fully utilizing the core because the single thread spends a lot of time on the IO. This is more of a limitation of our implementation rather than a limitation of Python.
> # Given a machine with multiple cores, single Python process could only utilize one core.
> In this task we will only address 1. 2 will be good for future optimization.
