A flexible distributed key-value database that is optimized for caching and other realtime workloads.

For developers, who are building real-time data-driven applications, Redis is the preferred, fastest, and most feature-rich cache, data structure server, and document and vector query engine.

Multipurpose C library and persistent key/value storage

Enough works to use this in production

Haskell bindings for libmdbx

DoubleClique is a high‑performance, in‑memory, replicated key–value store that runs on Dolphin’s PCIe interconnect using the SISCI API.

Multithreaded LSM-tree “kiwi” (pthreads, mutexes, condition variables) and LKL VFAT journaling with printk and gdb.

A Flexible Storage Framework for HPC

Key-value in-memory DB that does not (yet) saves it state on restart. Fast though.
