Datahike
A durable Datalog database with Datomic-compatible APIs, immutable snapshots, and distributed architecture.
What is Datahike?
Datahike is a durable, versioned Datalog database that provides Datomic-compatible APIs with git-like semantics. It is built on persistent data structures, enabling immutable database snapshots that can be shared and queried without locks, making it suitable for complex relationship modeling and historical data analysis.
Developers building applications that require complex relationship modeling (e.g., social networks, knowledge graphs, supply chains), historical data analysis, audit trails, or GDPR compliance, particularly those using Clojure, ClojureScript, JavaScript, or Java across JVM, Node.js, or browser environments.
Developers choose Datahike for its immutable, time-travel capabilities, flexible storage backends (file, LMDB, S3, JDBC, etc.), and distributed design that allows read scaling without database connections. Its Datomic-compatible API and cross-platform support provide a production-proven alternative with git-like semantics for versioning and branching.
Overview
Versioned, fast, distributed Datalog engine for everyone.
Use Cases
Best For
- Building applications with complex graph-like relationships where Datalog's pattern matching simplifies queries over traditional SQL joins.
