Irmin
Irmin is an OCaml library for building mergeable, branchable distributed data stores using Git-like principles.
What is Irmin?
Irmin is an OCaml library for building mergeable, branchable distributed data stores. It applies Git-like version-control principles—such as cloning, branching, pushing, and pulling—to programmatically managed data, enabling automatic conflict handling and scalable synchronization across nodes. It solves challenges in distributed systems by providing customizable storage layers and data structures.
Developers building distributed systems, unikernel applications (especially with MirageOS), or data-intensive services requiring versioned, auditable, and mergeable data stores. It's particularly suited for those needing fine-grained control over consistency and storage backends.
Irmin offers a unique blend of Git-like semantics with formal distributed systems foundations, including support for Conflict-free Replicated Data Types (CRDTs). Its modular, library-based design allows developers to tailor the database to specific CAP theorem trade-offs, and its portability across environments—from browsers to unikernels—sets it apart.
Overview
Irmin is a distributed database that follows the same design principles as Git
