KeyDB

This is a repackaged open source software product wherein additional charges apply for cloudimg support services.

Overview

KeyDB is a high performance, fully open source fork of Redis that adds multithreading, allowing a single node to use all of the cores on your instance and serve far more operations per second than single threaded Redis on the same hardware. KeyDB speaks the Redis protocol and is a drop in replacement for Redis, so your existing Redis clients, libraries and tooling work unchanged. This image delivers KeyDB fully installed and configured as a system service, so a production grade in memory data store is running within minutes of launch.

Application Stack

The KeyDB server installed from the official project package and run by the bundled systemd service. The database bound to port 6379 with protected mode disabled and password authentication enforced. Append only file persistence enabled so writes survive a restart. The persistence directory placed on a dedicated, independently resizable EBS data volume so the data set is kept off the operating system disk.

In Memory Data Store

Use KeyDB as a cache, a session store, a message broker, a rate limiter, a leaderboard, or a primary key value store. It supports the full Redis data model including strings, hashes, lists, sets, sorted sets, streams, bitmaps and hyperloglogs, along with pub/sub, transactions, Lua scripting and keyspace notifications. Multithreading lets a single instance saturate modern multi core hardware.

Secure First Boot

On the first boot of your instance a one shot service generates a fresh strong password, unique to that instance, sets it as the KeyDB requirepass and writes it to a root only file. No shared or default credentials ship in the image and the database refuses unauthenticated connections.

Ready To Use

Connect from your application or from the bundled keydb-cli using the generated password. Point your existing Redis client libraries at the instance on port 6379 with the password and they work without code changes. The append only file and snapshots live on the dedicated data volume.
