@stuartcarnie @alamb I was doing this pull request and realized that the current join fuzz testing currently only supports i32.

I could make a follow up to use a macro to create tests for each type but I would need to take a look at how long the tests are taking. What do you think a good threshold would be for testing time?

@jonathanc-n maybe we don't need each type? i would focus on int64, decimal and Utf8(View), since these are likely most common join keys.

Thank you @jonathanc-n and @findepi

I agree it might be worth figuring out some way to expand coverage that doesn't require so many individual tests to be added / updated 🤔
