Learn more. since we are already using failOnErr, can we simply use this boolean instead of evalmode struct? what are you thoughts? There was a problem hiding this comment. Choose a reason for hiding this commentThe reason will be displayed to describe this comment to others. Learn more. Hi, thanks for your review! The intention why it is done this way is that in the Rust code the ansi mode is always treated the same way whether the expression supports the three ansi modes or only two. If not, we have to do a different treatment for both cases. |

It would be nice if Arrow/DataFusion threw a specific overflow error so that we didn't have to look for a string within the error message, but I guess that isn't available.

I am going to file a feature request in DataFusion. I will post the link here later.

Great! I understand that we have to wait for the next version of arror-rs to be released and integrate it here to be able to make the changes, right?

We can continue with this and do a follow up once the arrow-rs change is available. Or you can wait; the arrow-rs community is very responsive.

Probably better to do it in a follow-up PR, I think. Thanks!

Apparently my PR in Arrow will not be available for 3 months because it is an API change 😞

When we upgrade to the version of the arrow with the improved overflow eror reporing then the tests in this PR will fail (because we are looking for
ComputeError
but instead will getArithmeticOverflow
) so I don't think we need to file an issueThere was a problem hiding this comment.
