Hi
@Erez Shinan, follow up of my PR.
It sounds like we also need to support UUID x Text?

TypeError: Incompatible types for column 'owner_id': String_UUID() <-> Text()

On my use case, it happens between MySQL UUID <> Redshift Text.
I am not sure where UUID fits the class Dialect object though

Any update on this issue? I'm seeing this happen on Postgres where the column is being converted to "String_UUID" in one table, but is classified as "Text" in the other table due to detection of non-UUID values.

Hi @timothyhinh79, we're not currently working on this but may in the future, in the meantime we'd happily accept a community contribution

@dlawin - I had this exact issue when comparing snowflake and postgres and I was able to come up with a simple approach that will overcome this issue in my fork. May be that can help. I will push it out and hopefully it can overcome your issue too.

I still encounter this issue on the latest version (0.9.9) ...

I think once we get #762 worked out, it will resolve this issue too

@MattDelac do you get this warning?

Mixed UUID/Non-UUID values detected in column {'.'.join(table_path)}.{col_name}, disabling UUID support

No now I get the following when I compare UUID (MySQL) to BINARY (Snowflake)

Hi @MattDelac,

I'm sorry for the delay in following up on this. Thank you for taking the time to open this PR!

We made a hard decision to sunset the data-diff package and won't provide further development or support.

W.r.t UUID x Text diffing. If that helps at all, we currently support it in Datafold Cloud with the caveat that upper/lower casing and "-" characters should match.
