public class BeamSideInputJoinRel extends BeamJoinRel
BeamJoinRel
which does sideinput Join
This Join Covers the case:
sideInput
is utilized to implement the join, so there are some constraints:
FULL OUTER JOIN
is not supported.
LEFT OUTER JOIN
, the unbounded table should on the left side.
RIGHT OUTER JOIN
, the unbounded table should on the right side.
General constraints:
BeamJoinRel.ExtractJoinKeys
condition, joinInfo, joinType, variablesSet
