Hi all,
Considering the Join condition 'CAST(IS_NOT_DISTINCT_FROM($1, $2),
BOOLEAN)', which cast the non-nullable BOOLEAN to nullable BOOLEAN, Calcite
can not split out equiv predicate, thus some join operation like hash join
/ sort merge join may not be used. Maybe we can
expand

Yes, you got the semantics correct.
There are 6 kinds of events that can happen: create, update, delete of
order_item, and create, update, delete of product. Some of these are not
possible - e.g. creating a product with the same id after you have created an
order - because of primary and
Yep I think you got the idea.

I've read again parts of the paper and now I've finally got the idea, I
hope. The semantics still works with plain relations, relational operators
are applied as in instantaneous queries, just the resulting relation is
"streamed", in case of EMIT STREAM clause in the form of records and

Hi
Now the default "expand" in SqlToRelConverter.ConfigBuilder is true but in
calcite's main process, actually, it is false(
`withExpand(THREAD_EXPAND.get())`)

That leads we need to explicitly set `withExpand` to false when we use
SqlToRelConverter.
So
