[upd]: Keydb Eng
Redis uses a single main thread to process all commands. While this simplifies internals (no locks, predictable performance), it leaves modern multi-core CPUs underutilized.
KeyDB’s lightweight data structures and support for ARM architectures make it well‑suited for IoT devices that accumulate time‑series data or need to queue commands for remote execution.
: Distributes work across all available CPU cores to maximize hardware efficiency.
: Unlike Redis's primarily single-threaded event loop, KeyDB runs the event loop on multiple threads. Network I/O and query parsing are performed concurrently, allowing it to outperform Redis on a per-node basis. Active Replication keydb eng
Using Conflict-free Replicated Data Types (CRDTs), KeyDB allows active-active replication between geographically separated data centers. This ensures that if one data center goes down, the other can continue accepting writes immediately, providing superior disaster recovery [4]. 2. Flash Storage Support (KeyDB Pro)
Storing HTML fragments, sessions, or API responses for rapid retrieval. Real-time Analytics: Processing high-velocity data streams using structures like HyperLogLogs Geospatial indexes Message Brokering:
Snap Inc., the parent company of Snapchat, deployed KeyDB on Google Cloud to reduce cross‑cloud latency between their AWS and Google Cloud regions. Before KeyDB, the average P99 latency was between 49 and 133 milliseconds. After implementing a KeyDB cache, cache hits dropped latency to just 1.56‑2.11 milliseconds – a reduction of up to . This allowed Snap to perform real‑time data analysis across their multi‑cloud estate for the first time. Redis uses a single main thread to process all commands
If you are looking to "develop a feature" for it—likely an automation script or an integration to keep these keys updated—here is the technical breakdown:
KeyDB is utilized by various organizations globally to power critical infrastructure. According to data from TheirStack , companies across several industries rely on the engine for its speed: (Software Development) Sekoia.io (Cybersecurity) Bukalapak (E-commerce/IT Services) HENZ ICT (Consulting)
📡 Storing user state for web applications that require sub-millisecond response times. : Distributes work across all available CPU cores
KeyDB was created by EQRIVER (now a part of Snap Inc.) to solve scaling bottlenecks in their own infrastructure, leading to a system that is often than Redis on the same hardware [1, 2]. The Architecture: Why Multithreading Matters
The engineering effort has paid off handsomely. Early benchmarks showed a single KeyDB instance achieving just over five times more operations per second than a single Redis instance, with nearly five times lower latency. Even when running with a single thread, KeyDB holds about a five percent performance advantage over Redis, thanks to careful optimisations in the codebase.
