What is Olric?

Distributed cache and in-memory key/value data store. It can be used both as an embedded Go library and as a language-independent service.

With Olric, you can instantly create a fast, scalable, shared pool of RAM across a cluster of computers.

Features:

• Designed to share some transient, approximate, fast-changing data between servers,
• Embeddable but can be used as a language-independent service with olricd,
• Supports different eviction algorithms,
• GC friendly storage engine,
• Fast binary protocol,
• Highly available and horizontally scalable,
• Provides best-effort consistency guarantees without being a complete CP (indeed PA/EC) solution,
• Supports replication by default (with sync and async options),
• Quorum-based voting for replica control (Read/Write quorums),
• Supports atomic operations,
• Supports distributed queries on keys,
• Provides a plugin interface for service discovery daemons,
• Provides a locking primitive which inspired by SETNX of Redis.

This version includes many new features and bug fixes:

* Initial implementation of DTopic data structure,

* Olric Binary Protocol reimplemented. Now it's very easy to define new message types.

* Improved Kubernetes integration: https://github.com/buraksezer/olric-kubernetes
