Masayuki Takahashi commented on CALCITE-2173:
---------------------------------------------
I am very glad that you comment and care for this. Thanks. I think I have many
issues for this.
- Add ArrowAggregation, ArrowJoin, ArrowUnion, etc..
- What kind of data to read (Feather, from Parquet, etc..)
- Rethinking about ArrowRexToLixTranslator because it breaks RexToLixTranslator
in core module
> What are your thoughts on how this could be added to Calcite?
Since many issues are still remain, I don't think that yet :-)
Now, I would be happy if you could tell me about the points to improve about
how to implement to scan for column store storage like Apache Arrow in Calcite.
Or I would be very happy if this implementation got some help from someone.
> By the way, in order to get it to build, I had to make a minor change:
Thanks! I will pull it.
