Tightening of pydantic dependancy following release of v0.11.1

[Francis Chmiel]

Describe the bug
The recent release changed the dependency of pydantic from "1.10.12" to ">=1.10.12".

This is causing pipelines using data-diff to break, because of breaking changes with pydantic in version 2.

Would this version be more appropriate:

pydantic = ">=1.10.12, <2.0.0"

[Francis Chmiel]

Appreciate the stance outlined here.

We don't use pydantic in our service and it feels peculiar for us to restrict a transitive dependency, but that may be my misunderstanding.

Experiencing the exact same issue. Can confirm data-diff 0.11.1 with the redshift extra is broken.

[Daan Luttik]

Same issue here (now with data-diff 0.11.1 and the snowflake extra). Adding pydantic = ">=1.10.12, <2.0.0" explicitly indeed seems to resolve the issue.

Yeah I would argue its annoying for me to have to restrict a transitive dependancy, so hoping we can restrict within this package.

Hi @FChmiel et al,

I'm sorry for the delay in responding. Thank you for trying out data-diff and for opening this issue!

We made a hard decision to sunset the data-diff package and won't provide further development or support. Diffing functionality will continue to be available in Datafold Cloud. Feel free to take it for a trial or contact us at [e-mail] if you have any questions.
