> I think there are two pieces:
> - the separate parallel unit (always a Scan for Phoenix)
> - the reader class to instantiate that will interpret the results.
> It be pretty easy to write code that combines multiple Scans together too, based on the start row/end row in the case that Phoenix over-parallelizes due to guideposts.
> FWIW, even the Phoenix DML (UPSERT SELECT and DELETE) fit this model of a Scan plus the reader code which would push the data back out for the writes (see UpsertCompiler and DeleteCompiler).
