[jira] [Work logged] (BEAM-6114) SQL join selection should be done
in planner, not in expansion to PTransform
[ https://issues.apache.org/jira/browse/BEAM-6114?focusedWorklogId=168662&page=com.atlassian.jira.plugin.system.issuetabpanels:worklog-tabpanel#worklog-168662 ]

Work Description: kennknowles opened a new pull request #7121: [BEAM-6114] Add isBounded() to BeamRelNode and BeamSqlTable, use for JOIN
URL: https://github.com/apache/beam/pull/7121
Adds boundedness information to the SQL/Calcite planner's relational algebra representation and uses it to select a join transform.
This builds on #7118 which separates the lookup join into its own PTransform. In this PR, the non-lookup side input join and "standard" join are also made into separate PTransforms.

> Currently Beam SQL joins all go through a single physical operator which has a single PTransform that does all join algorithms based on properties of its input PCollections as well as the relational algebra.
> A first step is to make the needed information part of the relational algebra, so it can choose a PTransform based on that, and the PTransforms can be simpler.
> Second step is to have separate (physical) relational operators for different join algorithms.
