Keydb Eng ((full)) Official

Because KeyDB stays in sync with upstream Redis development, it is a superset of Redis functionality. You get everything Redis offers, plus the performance and features that modern applications need.

To handle split‑brain scenarios where the connection between nodes is severed, KeyDB timestamps every write. When the connection is restored, the most recent write wins, preventing stale data from overwriting newer values. keydb eng

A common misconception is that KeyDB is "lock-free." It is not. Instead, KeyDB uses (also known as hashed sharding). Each database key maps to a specific partition. A thread acquires the lock for only that partition, allowing other threads to operate on different partitions concurrently. Because KeyDB stays in sync with upstream Redis

KeyDB is an open-source, NoSQL key-value database that is designed to provide high-performance data storage and retrieval. It's a fork of the popular Redis database, with a focus on improved performance, scalability, and reliability. KeyDB is built around a simple, yet powerful data model that allows developers to store and retrieve data using a key-value pair. When the connection is restored, the most recent

For those who prefer a more familiar topology, KeyDB also supports traditional master‑replica clustering. Each data shard consists of one master node and at least two replicas. Replicas asynchronously replicate data from the master, and if the master fails, the healthiest replica automatically initiates an election to become the new master.

Unlike standard Redis, which often requires a proxy for TLS, KeyDB has native, multi-threaded TLS support. Critically, the TLS handshake runs on I/O threads, preventing the overhead from blocking the main execution thread.
