Delta Forge brings PostgreSQL to Delta Lake and Apache Iceberg. Run CREATE TABLE, INSERT, UPDATE, DELETE on both formats. Time travel through versions. UniForm interoperability. All from SQL. Deploy on the environment of your choice: your datacenter or your cloud.
No configuration. No cluster setup. Just connect and query. Watch Delta Forge transform how you work with Delta Lake.
One binary, zero configuration needed
PostgreSQL syntax plus Delta Lake commands
Time travel, VACUUM, OPTIMIZE - all via SQL
A single binary that writes Delta Lake natively and layers Apache Iceberg on top via UniForm. No drivers, no adapters, no format lock-in.
PIPELINE, VACUUM, OPTIMIZE, and time travel as first-class commands. Full PL/pgSQL, window functions, CTEs, and 200+ built-in functions.
Full Delta Lake protocol with Iceberg V1/V2/V3 layered via UniForm. Write Delta natively, expose Iceberg automatically. No ETL copies.
Starts in milliseconds, serves queries immediately. No warm-up, no resource planning.
Same binary on AWS, Azure, GCS, on-premises, or air-gapped environments. Your data stays on your infrastructure. No vendor telemetry, no cloud dependency.
Native Delta Lake engine with ACID transactions, time travel, and schema evolution.
