public class BeamCoGBKJoinRel extends BeamJoinRel
A BeamJoinRel which does CoGBK Join

This Join Covers the cases:

  • BoundedTable JOIN BoundedTable
  • UnboundedTable JOIN UnboundedTable

A CoGBK join is utilized as long as the windowFn of the both sides match. For more info refer BEAM-3345

General constraints:

  • Only equi-join is supported.
  • CROSS JOIN is not supported.

  • Nested Class Summary
