KeyDB Open Source

KeyDB Open Source is the fastest in-memory database in the world!

Run KeyDB on-prem yourself. It’s free and open source with over 1million downloads. KeyDB is an
actively maintained project that is growing fast!

What to expect from KeyDB Open Source?

Low latency

By keeping data in-memory, KeyDB can serve up data with submillisecond latencies

A variety of data structures

A variety of data structures are supported such as strings, hashes, lists, sets, sorted sets, bitmaps, hyperloglogs, geospatial indexes, and streams

Scalability

Add more throughput with replica nodes, active-replica nodes, or partition the data in a sharded cluster

High throughput

KeyDB is meant to handle high work loads with an architecture that maximizes use of your systems resources. A single node benchmarks over 1 million ops/sec

Basic persistence options

Periodically dump the dataset to disk or by appending each command to a disk-based log

High Availability

Simplify your high availability setup with active-replica nodes that do not require sentinel nodes for failover. HA setups are also available for sharded cluster mode configurations

KeyDB is a faster, drop in alternative to Redis

While fully compatible with Redis protocol, API,modules and clients, KeyDB is built on a multithreaded
engine that offers a powerful superset of functionality

Cross Region Multi-Master
Support

Run multiple master nodes replicated asynchronously to eachother with a last write wins methodology. This enables support of a single replicated dataset where all nodes are masters with no need for sentinel monitoring nodes.

Vertical and horizontal scaling

KeyDBs multithreading enables you scale vertically, maximizing the resources of your machine before scaling out horizontally. It is a great option for those reaching the current limitations of their Redis instance. Effectively use up to 10 cores with a standard KeyDB node and 16 cores with TLS enabled!

Better EXPIRation

KeyDB offers Subkey EXPIREs which enables expiration of members within a set. EXPIREs now also have near real time active deletion that removes major lags associated with old models of removing expired keys.

TLS Encryption

KeyDB now offers TLS support that can operate at 7x the throughput of Redis + TLS

While TLS encryption adds additional CPU overhead, KeyDB’s multithreaded architecture enables more worker threads to prevent any decline in performance.

ModJS

Create your own commands with KeyDB’s open source javascript module. Built on the powerful V8 JIT engine, ModJS is faster than LUA and supports many node.js modules to offer extensive library support for common tasks

ARM Support

KeyDB is built for ARM. KeyDB uses the available cores with its multithreaded architecture and is a very fast and lightweight database.
