> BEAM-4020 introduces HBaseIO reads based on SDF. So far the read() method still uses the Source based API for two reasons:
> 1. Most distributed runners don't supports Bounded SDF today.
> 2. SDF does not support Dynamic Work Rebalancing but the Source API of HBase already supports it so changing it means losing some functionality.
> Once there is improvements in both (1) and (2) we should consider moving the main read() function to use the SDF API and remove the Source based implementation.
