[DataCatalog2.0]: `Protocol` abstraction for `DataCatalog` #4160

ElenaKhaustova · 2024-09-12T21:49:27Z

Description

This introduces the Protocol abstraction for the current DataCatalog, which will be used to add new catalog implementations. Currently, it fully relies on the existing DataCatalog implementation to avoid breaking changes.

Development notes

Protocol class was excluded from test coverage since its method placeholders were marked as untested, see the related issue: nedbat/coveragepy#1616

HUGE!

So neat and self-contained and best of all - non-breaking! If all references to DataCatalog are replaced with CatalogProtocol, I think it looks ready to merge for me.

My original understanding this is going to be a separate Catalog, but I see this PR has a lot of changes to existing API's typehint so I am slightly confused.

Does type hint suppose to work here? As it seems like it doesn't understand the catalog at all as all the IDE features seems broken.

Question: Is this how type hint supposed to be done with Protocol? I roughly understand how Protocol works like traits/interface but I haven't seen much in a real codebase.

Yep, cause this is type in the end, see examples here: https://peps.python.org/pep-0544/#protocol-members

@noklam

Hmm, it seems working well in PyCharm and mypy does not complain as well.

The new catalog is added in the following PR. But first we need this to fit two implementations together. Here is a context regarding this decision: #4151 (comment)

noklam

Overall looks good to me. I find CatalogProtocol slightly weird, I don't know what's the convention is for Python, I found a list here: python/typeshed#4174

approved as non-blocking commenet

merelcht

This mostly looks good, but I left a comment about the methods added here that will be removed in the future.
