Using SQL as catalog is not new (iceberg supports JDBC catalog from the very beginning). The main difference is to store metadata and stats also directly in SQL databases, which makes perfect sense for smaller scale data. In fact we were doing something similar in https://github.com/Mooncake-Labs/pg_mooncake, metadata are stored in pg tables and only periodically flush to actual formats like iceberg. |
