Benchao Li commented on CALCITE-5381:
-------------------------------------
This is an interesting issue. This makes me thinking about what the
compatibility should the {{RelBuilder}} guarantee. Currently it seems that we
only care about the "API compatibility", but not "result compatibility".
I believe that there are more cases that we changed the result for some methods
of {{RelBuilder}} without considering compatibility problems.
[~Sergey Nuyanzin] Could you kindly elaborate a little more about the situation
you are in now? Or linking to a Flink issue would help a lot for us. I'm
thinking that whether we can use some other methods instead of
{{RelBuilder#join}}, e.g. {{RelBuilder#correlate}}?

> Key: CALCITE-5381
> URL: https://issues.apache.org/jira/browse/CALCITE-5381
> Project: Calcite
> Issue Type: Improvement
> Components: core
> Reporter: Sergey Nuyanzin
> Priority: Major
>
> The issue is that the change done in
> https://issues.apache.org/jira/browse/CALCITE-4668 is not supported now in
> Flink and requires some significant efforts to make it working.
> At the same time we would like to move forward with Calcite update.
> Currently there is no way to turn this off via property e.g. or via
> overriding of methods.
> This jira issues proposes introducing such property (turn on by default)
> turning off means Calcite 1.27.0 behavior
