An open lakehouse
Tables in the open Iceberg format, behind a standard catalog, on object storage you choose. Any engine that speaks Iceberg can read them, and every write is a snapshot you can return to.
Open format, standard catalog
Tables are Apache Iceberg behind an Iceberg REST catalog, on S3-compatible storage over MinIO or native buckets.
Every write is a snapshot
Appends, overwrites, upserts and merges are ACID. Each one produces a snapshot you can tag, query by time, branch from or roll back to.
Schemas change safely
Columns can be added, dropped, renamed and reordered, and partitioning can evolve without rewriting the table.
Governance travels with the query
Row and column rules are applied when the query is planned, so every surface that reads a table gets the same narrowed answer.
