Hi Jin,
We wanted to transform LogicalJoin to different Join Types in the external
system depending on the LogicalJoin Child Properties(which are in external
convention).
As LogicalJoin can be a child of LogicalJoin, because of VolcanoPlanner's
top-down approach, the child LogicalJoin is not
If I understand correctly, you can try below steps:
1. Create a rule of Converter to convert child nodes to append external
Convention;
2. Create a rule of RelOptRule to convert the parent node -- check the
Convention of child node when matching
Is it applicable ?

Hi all,
May I have the contributor permission for Calcite project? I’d like to work on
some issue related to VolcanoPlanner. Thanks.

Hi,
there are some SQL dialect grammars online here (for ANTLR4)

If you are going to do all that work to translate to ANTLR, one thing that may
help is to re-use SqlParserTest.java. (Shouldn’t be hard to translate that into
javascript, or your could use a harness that calls the javascript code from
java.) Your code may be entirely different, but the tests
Hi,
The properties of the child nodes correspond to the external Convention.
So, the child nodes have to be converted before the parent can be
transformed.
If the property doesn't match (or) if the property cannot be
determined(child node not converted), the rule cannot be applied. So, we
end up
It is not using ANTLR. Since our goal is specifically to support parsing
and manipulation of SQL in the frontend, we use

have some pretty big ANTLR grammars for other (non-SQL) use cases and this
approach definitely feels

I guess in Rahul's case, the child node of join should be converted first,
thus physical properties will be appended.
But RelNode doesn't have a reference to parent, thus an independent
RelOptRule is needed to convert LogicalJoin.
Just as Michael said, you need to override the method of

I once needed to fix this issue [1] but the fix was rejected because it
introduced worse performance than it ideally should. As mentioned in the
comments, the current approach followed in the current parser is the reason
for that. I mean if we designed the grammar differently, we could've had
Thanks, Julian.
I agree this would be a huge work, but I have to do this, I’m just wondering if
any fellows here have the similar requests.
