      Description

      We use BeamSQL to run streaming jobs mostly, and add a join_as_lookup improvement(internal branch) to cover the streaming-to-batch case(similar as [1]). I could submit a PR as experimental if people are interested.

      The rough solution is, if one source of join node implements BeamSeekableTable and the other is not, then the join node is converted to a fact-lookup operation.
