Introduction

Welcome to Real World Irmin. This book is all about Irmin.

Irmin is an OCaml library for building mergeable, branchable distributed data stores.

• Built-in Snapshotting - backup and restore
• Storage Agnostic - you can use Irmin on top of your own storage layer
• Custom Datatypes - (de)serialization for custom data types, derivable via ppx_irmin
• Highly Portable - runs anywhere from Linux to web browsers and Xen unikernels
• Git Compatibility - irmin-git uses an on-disk format that can be inspected and modified using Git
• Dynamic Behavior - allows the users to define custom merge functions, use in-memory transactions (to keep track of reads as well as writes) and to define event-driven workflows using a notification mechanism
