[GitHub] [beam] kennknowles opened a new issue, #19178: support OR

kennknowles opened a new issue, #19178:
URL: https://github.com/apache/beam/issues/19178

   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.
   
   Imported from Jira [BEAM-7149](https://issues.apache.org/jira/browse/BEAM-7149). Original Jira may contain additional context.
   Reported by: amaliujia.
   Subtask of issue #19175
