Nessie

Transactional catalogue for data lakes with Git-like semantics

About Nessie

A transactional catalogue for Apache Iceberg and other tables that provides Git-like branching and versioning across a data lake, enabling isolated changes and atomic commits across tables. Its open development model means documentation, plugins and community support are publicly available, and organisations can contribute fixes upstream instead of waiting on a vendor roadmap. For many teams it becomes long-lived infrastructure: simple to back up, straightforward to automate and independent of per-seat pricing as usage grows steadily.
