Hi! I wonder if spicedb can fit our need...

would you share your requirements?

we have a lot of DBs, a lots of apps, redis, redshit, cloud formation - you name it. We need to build the system which can organise the categorization of data - public, internal, conf, etc - and grant permissions based on roles and attributes. Plus we need to keep the category of data when it travels via airflow and similar tools.

well I don't see anything in there that seems couldn't be modeled with SpiceDB. SpiceDB supports both RBAC models and ABAC models if you want attributes too, and you can mix and match. I don't know exactly what you mean "keep the category of data", but: SpiceDB offers an API to basically listen to the stream of changes in it's own internal database, so you can then stream back into your data streaming pipelines
