Why the models rank Apache Gravitino — on best open-source lakehouse catalog tools
“The strongest "catalog of catalogs" — a graduated Apache top-level project that federates Hive Metastore, Iceberg REST, JDBC sources, messaging, and filesets under one metadata layer, which is the real-world problem most enterprises actually have (heterogeneous metadata sprawl, not a greenfield Iceberg deployment); near-tie with Polaris depending on whether you need federation or a single clean Iceberg catalog.”
