Thanks for the response!
We are trying to reduce that number too. But first, we decided to ingest all production OLAP DBs, build lineage, and then prepare cases to motivate businesses to change data architecture.
We are a holding company with about 40 businesses and have a pretty weird data architecture with multiple table replicas. Now I am wondering around ~3000 tables that are replicated at least a few times each. (Max 75 replicas per table, minimum 1)
I have never seen such a monster before. So, trying to put it into perspective compared to community.
