> Interval join support no equi-condition
> ---------------------------------------
>
> Key: FLINK-15408
> URL: https://issues.apache.org/jira/browse/FLINK-15408
> Project: Flink
> Issue Type: Improvement
> Components: Table SQL / Runtime
> Affects Versions: 1.10.0
> Reporter: hailong wang
> Assignee: hailong wang
> Priority: Major
> Labels: pull-request-available
> Fix For: 1.12.0
>
>
> 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}
