@bosd I'm not sure I understand why you depend on attribute_set here. You want to build a supercharged attribute_set module with JSONB, right? That sounds legit but should this be done inside the server-tools base_sparse_fields_jsonb module? Wouldn't it be better to leave base_sparse_fields_jsonb without attribute_set dependency and create another attribute_set_jsonb module in OCA/odoo-pim or make attribute_set depend on base_sparse_fields_jsonb eventually?

Disclaimer I didn't read your code carefully yet.

@rvalyi I was indeed contemplating about this. Placing it in a separeate module in the pim repo would keep this base implementation more basic, clean and flexible. But there are some more modules / improvements to get to a full working stack. Wanted to prevent, that we end up with a lot of glue modules and puzzle to get it up and running.

I will later separate the latest commits and place it in their own module.

This module as it sits here, could potentially be merged into base_sparse, but for now i think it is better to keep it separate.

@bosd this starts to look pretty solid. kudos for the work! I would say what is missing for now are some tests inside this module. You can probably adapt some tests from the original module https://github.com/odoo/odoo/blob/19.0/addons/base_sparse_field/tests/test_sparse_fields.py
