> For Now, Interval join must has at least one equi-condition. Should we need to allow no equi-condition like regular join?
> For that, if sql like as follow:
> {code:java}
> INSERT INTO A SELECT * FROM B join C on B.rowtime BETWEEN C.rowtime - INTERVAL '20' SECOND AND C.rowtime + INTERVAL '30' SECOND
> {code}
> It will has no matched rule to convert.
> {code:java}
> Caused by: org.apache.calcite.plan.RelOptPlanner$CannotPlanException: There are not enough rules to produce a node with desired properties: convention=STREAM_PHYSICAL, FlinkRelDistributionTraitDef=any, MiniBatchIntervalTraitDef=None: 0, UpdateAsRetractionTraitDef=false, AccModeTraitDef=UNKNOWN.
> Missing conversion is FlinkLogicalJoin[convention: LOGICAL -> STREAM_PHYSICAL]
> {code}
