Maryann Xue commented on PHOENIX-154:
-------------------------------------
I think it would. We can even divide the work into two parts:
1) Runtime of sliding windows with ORDER BY key and ROWS/RANGE.
2) Integration with Calcite-Phoenix (the translation of calcite Window operator
into Phoenix runtime).
We do the same thing with implementation of nested-loop join in Phoenix as
well, as you can see we have a CorrelatePlan and then we have standalone tests
to check this runtime implementation. Besides, we have the compiler
implementation for the PhoenixCorrelate operator, and altogether we can run SQL
queries in our end-to-end tests.
Part 2 will be rather simple once part 1 is ready, and it does not require much
knowledge of Calcite either. Simply think of it as writing compiler code in
standalone Phoenix but without even having to worry about how it interacts with
the compiler framework. The workload of this part is more about writing
end-to-end test cases.
