Dolt

Dolt is a version control system for databases that combines the collaborative features of Git with SQL database functionality. Developers use it to track changes to database schemas and data, enabling branching, merging, and collaborative workflows for data management and engineering tasks. The tool is compatible with MySQL and MariaDB, allowing developers to work with SQL while leveraging version control capabilities. Dolt was developed by dolthub and is released under the Apache 2.0 license. The tool is written in Go and provides features for managing database versioning, distributing databases, and enabling decentralized collaboration on data projects, making it useful for teams that need to version control their databases as they would code repositories.

Dolt treats databases as versioned, collaborative assets that can be branched and merged like software repositories. This approach addresses the challenge of tracking data changes over time and coordinating modifications across team members. The immutable nature of Dolt's database design supports reproducibility and audit trails for data changes, which is valuable for data engineering workflows, AI applications requiring persistent memory, and scenarios where data history and accountability matter.
