public class BeamSideInputLookupJoinRel extends BeamJoinRel
A BeamJoinRel which does Lookup Join

This Join Covers the case:

  • SeekableTable JOIN non SeekableTable

As Join is implemented as lookup, there are some constraints:

  • FULL OUTER JOIN is not supported.
  • If it's a LEFT OUTER JOIN, the non Seekable table should on the left side.
  • If it's a RIGHT OUTER JOIN, the non Seekable table should on the right side.

General constraints:

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