Pika - nosql compatible with redis, it is developed by Qihoo's DBA and infrastructure team

•    C++

Pika is a persistent huge storage service , compatible with the vast majority of redis interfaces (details), including string, hash, list, zset, set and management interfaces. With the huge amount of data stored, redis may suffer for a capacity bottleneck, and pika was born for solving it. Except huge storage capacity, pika also support master-slave mode by slaveof command, including full and partial synchronization.

huststore - High-performance Distributed Storage

•    C

huststore is a open source high performance distributed database system. It not only provides key-value storage service with extremely high performance, up to 100 thousand QPS, but also supports data structures like hash, set, sorted set, etc. Also, it can store binary data as value from a key-value pair, and thus can be used as an alternative of Redis.In addtion, huststore implements a distributed message queue by integrating a special HA module, features including message Push Stream, and message Publish-SubScribe, these features can be used as replacements of the corresponding features in rabbitmq and gearman.

CurioDB - Distributed & Persistent Redis Clone built with Scala & Akka

•    Scala

CurioDB is a distributed and persistent Redis clone, built with Scala and Akka. Please note that despite the fancy logo, this is a toy project, hence the name "Curio", and any suitability as a drop-in replacement for Redis is purely incidental.

Vedis - An Embedded Implementation of Redis

•    C

Vedis is an embeddable datastore C library built with over 70 commands similar in concept to Redis but without the networking layer since Vedis run in the same process of the host application. Unlike most other datastores, Vedis does not have a separate server process. Vedis reads and writes directly to ordinary disk files. A complete database with multiple collections, is contained in a single disk file.

elasticell - Elastic Key-Value Storage With Strong Consistency and Reliability

BadgerDB - Fast key-value store in Go.

•    Go

BadgerDB is an embeddable, persistent, simple and fast key-value (KV) store, written purely in Go. It's meant to be a performant alternative to non Go based key-value stores like RocksDB. It is written out of frustration with existing KV stores which are either written in pure Go and slow, or fast but require usage of Cgo. Badger aims to provide an equal or better speed compared to industry leading KV stores (like RocksDB), while maintaining the entire code base in pure Go.

DiskCache - Python disk backed cache (Django-compatible). Faster than Redis and Memcached. Pure-Python

•    Python

DiskCache is a disk and file backed cache library, written in pure-Python, and compatible with Django. The cloud-based computing of 2021 puts a premium on memory. Gigabytes of empty space is left on disks as processes vie for memory. Among these processes is Memcached (and sometimes Redis) which is used as a cache. It is good to use empty disk space for caching.

FoundationDB - Distributed, Transactional Key-value store

•    C++

FoundationDB is a distributed database designed to handle large volumes of structured data across clusters of commodity servers. It organizes data as an ordered key-value store and employs ACID transactions for all operations. It is especially well-suited for read/write workloads but also has excellent performance for write-intensive workloads. Users interact with the database using API language binding.
