KeyDB is an open-source, NoSQL database that was created as a fork of Redis, a popular in-memory data store. KeyDB is designed to provide high performance, low latency, and scalability, making it suitable for large-scale applications. While it's compatible with Redis, KeyDB has introduced several improvements and new features that enhance its performance and functionality.
Keydb_eng represents the evolution of in-memory data management. By bringing a multithreaded architecture to the robust Redis ecosystem, KeyDB provides a future-proof solution for engineers needing maximum performance without compromising on ease of use. Whether you are scaling an existing Redis setup or building a new high-throughput system, KeyDB is designed to meet the demands of modern infrastructure. keydb_eng
Each worker maintains its own aeEventLoop (async event library), epoll/kqueue fd set, and client list. KeyDB is an open-source, NoSQL database that was
This article explores what keydb_eng is, its key technological advantages, and why it is the go-to solution for high-performance engineering needs in 2026. What is KeyDB (keydb_eng)? Each worker maintains its own aeEventLoop (async event
Furthermore, KeyDB supports a new module called FLASH, which enables the use of both RAM and flash storage (NVMe/SSD) as a tiered storage solution. By offloading less frequently accessed data to flash storage, organizations can drastically reduce infrastructure costs while maintaining acceptable performance levels for warm data. This is particularly beneficial for datasets that are too large to fit entirely in RAM but require faster access than traditional disk-based databases can offer.
