Redis is an advanced key-value store. It is similar to memcached but the dataset is not volatile, and values can be strings, exactly like in memcached, but also lists, sets, and ordered sets. All this data types can be manipulated with atomic operations to push/pop elements, add/remove elements, perform server side union, intersection, difference between sets, and so forth. Redis supports different kind of sorting abilities.
It is possible to think at Redis as a data structures server, it is not just another key-value DB. Redis supports operations like atomic push and pop of elements on lists, taking ranges of elements from this lists at once, trimming of lists, server-side intersections of sets and even sorting data.

GridDB is an In-Memory NoSQL Database for highly scalable IoT applications . It has a KVS (Key-Value Store)-type data model that is suitable for sensor data stored in a timeseries. It is a database that can be easily scaled-out according to the number of sensors. High Reliability It is equipped with a structure to spread out the replication of key value data among fellow nodes so that in the event of a node failure, automatic failover can be carried out in a matter of seconds by using the replication function of other nodes.nosql key-value-store in-memory timeseries timeseries-database iot
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.key-value-store transactional acid distributed-database key-value database multi-model
SSDB is a high performace key-value(key-string, key-zset, key-hashmap) NoSQL database, an alternative to Redis. SSDB is stable, production-ready and is widely used by many Internet companies including QIHU 360. Its feature include Redis client support, Persistent queue service, LevelDB support, Built in CLI and lot more.ssdb nosql-databases leveldb nosql database key-value-store key-value redis-alternative
UnQLite is a in-process software library which implements a self-contained, serverless, zero-configuration, transactional NoSQL database engine. UnQLite is a document store database similar to MongoDB, Redis, CouchDB etc. as well a standard Key/Value store similar to BerkeleyDB, LevelDB, etc.database embedded-database json-database document-store key-value-store json mobile-database transactional
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.redis golang goleveldb support-cluster ledisdb rocksdb-support redis-alternative database key-value-store key-value

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.database in-memory key-value geospatial key-value-store
The Apache Accumulo sorted, distributed key/value store is a robust, scalable, high performance data storage and retrieval system. Apache Accumulo is based on Google's BigTable design and is built on top of Apache Hadoop, Zookeeper, and Thrift. Apache Accumulo features a few novel improvements on the BigTable design in the form of cell-based access control and a server-side programming mechanism that can modify key/value pairs at various points in the data management process.key-value key-value-store big-table distributed database aggregation
NanoStore is an open source, lightweight schema-less local key-value document store written in Objective-C for Mac OS X and iOS. Relational databases tend to have a rich understanding of the structure of your data, but requires some planing beforehand and some level of maintenance as well. NanoStore provides the flexibility that comes with key-value document stores, but still understands something about your data. Because the data is key-value based, it can be accessed quickly and can grow as much as needed... all without ever worrying about the schema.
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.architecture benchmark redis database-engine nginx message-queue distributed-storage
RocksDB is an embeddable persistent key-value store for fast storage. RocksDB builds on LevelDB to be scalable to run on servers with many CPU cores, to efficiently use fast storage, to support IO-bound, in-memory and write-once workloads, and to be flexible to allow for innovation. It is especially suited for storing data on flash drives. It has multi-threaded compactions, making it specially suitable for storing multiple terabytes of data in a single database.key-value-store flash-drive embedded-database database facebook
NutsDB is a simple, fast, embeddable and persistent key/value store written in pure Go. It supports fully serializable transactions and many data structures such as list、set、sorted set. All operations happen inside a Tx. Tx represents a transaction, which can be read-only or read-write. Read-only transactions can read values for a given bucket and given key or iterate over a set of key-value pairs. Read-write transactions can read, update and delete keys from the DB.key-value database data-structures
ApsaraCache is based on the Redis official release 4.0 and has many features and performance enhancements. ApsaraCache has proven to be very stable and efficient in production environment. ApsaraCache supports two main protocols of Memcached: the classic ASCII, and the newer binary. You can use ApsaraCache just as Memcached, and no client code need to be modified. You can persist your data by using ApsaraCache in Memcached mode just like Redis.redis database key-value redis-alternative key-value-store
Chronicle Map is a high performance, off-heap, key-value, in memory, persisted data store. It works like a standard java map yet it automatically distributes data between processes, these processes can be both on the same server or across your network. In other words its a low latency, huge data key value store, which can store terabytes of data locally to your process.distributed-caching cache key-value-store key-value
KeyDB is a high performance fork of Redis with a focus on multithreading, memory efficiency, and high throughput.
