------------------------------------

Hi [~boyuanz], I'm working in getting this issue done and I wanted to check on some things, I'm trying to get to the goal of converting BatchSpannerRead into a Splittable DoFn as a combination of GeneratePartitionsFn and ReadFromPartitionsFn. I'm doing it by combining both of them in a DoFn that takes a ReadOperation, generates the partitions and then process the partitions checking it with an OffsetTracker. Here is a draft PR with the change https://github.com/apache/beam/pull/14811, would this be the approach needed? Any comments will be appreciated if the approach is not the best.
