Project Nessie
Open-source transactional catalog for data lakes with Git-like semantics, branching, merging and versioning for Apache Iceberg and Delta Lake.
Our Verdict
Genuinely novel catalog for lakehouse workflows; adoption still early outside Dremio circles.
Pros
- Git-like branching for data lake tables
- Native Iceberg and Delta Lake support
- Enables safe experimentation via branches
- Open source under Apache 2.0
Cons
- Concept new to most data engineers
- Ecosystem tooling still maturing
- Operating Nessie yourself is non-trivial
- Dremio-adjacent branding limits neutrality perception
