etcd is a distributed, consistent key-value store for shared configuration and service discovery. It is simple, secure, fast and reliable. it uses the Raft consensus algorithm to manage a highly-available replicated log.


etcd - Distributed reliable key-value store for the most critical data of a distributed system

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.

BadgerDB - Fast key-value store in Go.

Fast, concurrent, evicting in-memory cache written to keep big number of entries without impact on performance. BigCache keeps entries on heap but omits GC for them. To achieve that operations on bytes arrays take place, therefore entries (de)serialization in front of the cache will be needed in most use cases. 

bigcache - Efficient cache for gigabytes of data written in Go.

Redcon is a custom Redis server framework for Go that is fast and simple to use. The reason for this library it to give an efficient server front-end for the BuntDB and Tile38 projects. Redcon has full TLS support.

Redcon - Redis compatible server framework for Go

BuntDB is a low-level, in-memory, key/value store in pure Go. It persists to disk, is ACID compliant, and uses locking for multiple readers and a single writer. It supports custom indexes and geospatial data. It's ideal for projects that need a dependable database and favor speed over data size.The desire to create BuntDB stems from the need for a new embeddable database for Tile38 and SummitDB.

Ledisdb is a high-performance NoSQL database library and server written in Go. It's similar to Redis but store data in disk. It supports many data structures including kv, list, hash, zset, set. LedisDB supports multiple different databases as backends.

Ristretto is a fast, concurrent cache library built with a focus on performance and correctness. Its features include Concurrency, High Hit Ratios, Fast Throughput, Cost-Based Eviction, Metrics support.

Ristretto - A high performance memory-bound Go cache

moss provides a simple, fast, persistable, ordered key-val collection implementation as a 100% golang library.moss stands for "memory-oriented sorted segments".

Bolt is a pure Go key/value store inspired by Howard Chu's LMDB project. The goal of the project is to provide a simple, fast, and reliable database for projects that don't require a full database server such as Postgres or MySQL.

Bolt -  An embedded key/value database for Go. 

A fast, high availability, fully Redis compatible store.


qdb - A fast, high availability, fully Redis compatible store.

 Package slowpoke is a simple key/value store written using Go's standard library only. Keys are stored in memory (with persistence), values stored on disk. Keys are stored in memory with persistence to disk. Values stored on disk only.

Slowpoke - Low-level key/value store in pure Go

 Package pudge is a fast and simple key/value store written using Go's standard library. Pudge is parallel. Readers don't block readers, but a writer - does, but by the stateless nature of pudge it's safe to use multiples files for storages.
