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.
