Catalog Preparation Guides

This directory contains the catalog preparation guides referenced from Prepare Lakehouse Catalogs. Each guide focuses solely on the steps required to provision the catalog and the supporting cloud resources (storage buckets, IAM roles, service principals). Once a catalog is prepared, see Configure Lakehouse Catalogs for how to wire it into the StreamNative Ursa compaction service.
