DataFusion 12.0.0 Release

Planning for DataFusion 12.0.0

• sqlparser 0.21 upgrade #3192
• Upgrade to arrow 21 #3225
• Fix some bugs in TypeCoercion rule #3407
• Fix the test failure of size_of_scalar failure on M1/M2 Mac #3398

Describe the solution you'd like
The usual schedule would have the RC cut on September 9th, but I plan on releasing it one week earlier, on September 2nd. This is partially due to the 9th being before the Labor Day weekend in the US, but also to line up with Dask SQL's planned GA release in September.

Describe alternatives you've considered
None

Additional context
None

should be arrow-datafusion 12.0.0?

Thanks, yes!

[andygrove]

I am no longer planning on releasing this early and will stick to the regular schedule, with the RC being created on September 9th.

@alamb @liukun4515 I updated the release checklist to include a few issues that are still open. I think it may be better to delay the release by a few days and get these bug fixes in, but I am also open to releasing without them and creating a new release in two weeks. What do you think?

[alamb]

I think the list of bugs looks good @andygrove -- I will apply extra effort later today and over the weekend to reviewing / helping them move along.

I don't have any particular driver to get the release out any earlier, but I think the community should probably weigh in (as we don't currently use the released versions of datafusion in my project, IOx)

agree with that.

I think the datafusion is not stable, and there are some bugs from type coercion migration.
We should find them and resolves them first.

It's better to add this pr to this plan for release #3396

@andygrove @alamb #3383
Shall this one also be resolved before 12?

[alamb]

@iajoiner I think it would be great to get #3383 resolved. However, since it is a test issue (rather than some issue with the underlying code) it is my opinion that it wouldn't hold up the release and we could release 12.0.0 even if #3383 were still open
