https://github.com/apache/arrow/pull/34939 adds an indexed access proxy for Arrow but the performance isn't great compared to properly adopting Arrow. It would be great to have Arrow support throughout the different clients...

Now that Arrow is used in a lot more places, I think it may be a good time to revisit this issue. The extra copies are introducing extra overhead in...

Oh nice. I guess you can't just remove the toArray call here for backwards compatibility? How good is Arrow/columnar data support in Plot these days?

That's great. I wonder whether for some databases that can stream/lazily evaluate results, slicing can be disabled. A database client could have a flag that says that results are lazily...

Thank you for adding the link to #352. This request is similar but not the same. It's to support Arrow in the specification and not just the implementation. I imagine...

Is there a plan for supporting this soon? It would be great to make the SQL support more robust and efficient.

@wiltsecarpenter did you make progress on this. Annie sent me a suggestion for the DuckDB client in https://observablehq.com/compare/357f1a71f976f173...ef33ae1a093daf79 and it's not using Arrow directly yet. Calling `.toArray().map((r) => Object.fromEntries(r))` is...

Vega now has time unit support so this should be doable.

Thank you for the clarification! Is that limitation documented somewhere? I couldn't find any mention in https://www.mat.unical.it/aspcomp2013/files/ASP-CORE-2.03b.pdf. Would it make sense to add a warning in gringo when numbers overflow...

> It might help, but it is not that easy to implement. A lot of places in the code would have to be adjusted. And the C/C++ language does not...
