Dear Calcite community:
I am new Calcite user here. I noted in the document
https://calcite.apache.org/docs/adapter.html that Calcite does support DDL

Hi jesusca
I am investigating how to extend MaterializedViewRule to support left outer
join. The first issue which I met is supporting outer join in
RelMdExpressionLineage#getExpressionLineage()
I think the current implementation also fits in the outer join case, and to
support outer join only ne
Hey Gavin,
I think you are bumping into a missing feature and most likely addressed by
[1].
The approach in [1] is rather good but I had some doubts about a few new
APIs that were introduced which made me a bit cautious about merging this
to master. I would definitely like to find some time to re
Hi Gavin,
A few more comments in case they help to get you a bit further on your work.
The need to return the result as a single object is a common problem in

Hibernate, etc.). Apart from the suggestions so far maybe you could loo
Ahh wow, thank you Stamatis. Great to know there is something that has been
done in the past
I suppose I could try to build from this PR and see if it works

I have made a customed JSONSchema on github :
https://github.com/guxiaobo/calcite-json-adapter,
I am still debug it, a simple example failed regarding getting the datatype of
tables:
Map> map = new HashMap>();
List t1 = new ArrayList();
JSONObject r1 = new JSONObj
It seems because the public RelDataType getRowType(RelDataTypeFactory
typeFactory) method of our JsonTable class did not have a change to be called.
