Summary: support OR
Key: BEAM-7149
URL: https://issues.apache.org/jira/browse/BEAM-7149
Project: Beam
Issue Type: Sub-task
Components: dsl-sql
Reporter: Rui Wang
OR supposed to be implement in rules.
Basically when LogicalRel is generated and being converted to PhysicalRel, OR
should be handled by a separate converter rule:
all conjunction clauses of OR should be converted to independent JOIN and their
results are combined by UNION rel with deduplication.
