Topics include schema evolution (no Parquet rewrites for column changes), multi-tenancy via partitioning, concurrency model (~100 TPS vs ~1 TPS for Iceberg/Delta), catalog options (PostgreSQL, MotherDuck, Quack protocol), upsert support via MERGE, caching behavior (RAM today, disk extensions coming), migration from Iceberg (metadata-only, files stay in place) and Delta (data move required), dbt/SQLMesh compatibility, time-series use cases, and maintenance via checkpoint/vacuum/compact commands. DuckLake is MIT-licensed and open source; MotherDuck is the managed commercial offering. ## Full article daily.dev links to this article rather than hosting it.
