Best Key-Value Databases for Redis

ArcadeDB allows you to manage complex models without any compromises. Polyglot Persistence is gone. There is no need to have multiple databases. ArcadeDB Multi-Model databases can store graphs and documents, key values, time series, and key values. Each model is native to the database engine so you don't need to worry about translations slowing down your computer. ArcadeDB's engine was developed with Alien Technology. It can crunch millions upon millions of records per second. ArcadeDB's traversing speed does not depend on the size of the database. It doesn't matter if your database contains a few records or a billion. ArcadeDB can be used as an embedded database on a single server. It can scale up by using Kubernetes to connect multiple servers. It is flexible enough to run on any platform that has a small footprint. Your data is protected. Our unbreakable fully transactional engine ensures durability for mission-critical production database databases. ArcadeDB uses the Raft Consensus Algorithm in order to maintain consistency across multiple servers.

Scale performance easily and cost-effectively as your app's traffic and demands increase. To handle thousands of simultaneous users at once, add a caching layer to your application architecture. All this while enjoying the benefits of a fully managed service. Superior throughput and performance to handle millions upon millions of requests per seconds with sub-millisecond latency. Fully managed service that provides automatic patching, updates and scaling. This allows you to focus on development. RedisBloom, RediSearch and RedisTimeSeries module integrations, supporting data analysis and search, as well as streaming. You get powerful capabilities like clustering, Redis on Flash, built-in replica, Redis on Flash, availability up to 99.99%, and more. Azure Cosmos DB and Azure SQL Database are available to complement your database services. This allows you to scale throughput at a lower price than expanding database instances.

Redis and Memcached are now more reliable, available, and scalable. Memorystore automates complex tasks such as patching, monitoring, failover, and high availability for open-source Redis and Memcached so you can spend more of your time programming. Start small and scale up your instance. Memorystore for Memcached supports clusters up to 5 TB, supporting millions of QPS with very low latency. Redis Memorystore instances are replicated across two zones, providing a 99.9% availability guarantee. Instances are monitored constantly and with automatic failover--applications experience minimal disruption. You can choose from two of the most popular open-source caching engines to build your application. Memorystore is protocol compatible and supports Redis and Memcached. Choose the engine that best suits your needs and budget.

ApsaraDB is an automated and scalable tool that developers can use to manage data storage shared between multiple applications, processes, or servers. ApsaraDB Redis is compatible with Redis protocol and offers exceptional read-write capabilities. It also ensures data persistence through the use of memory and hard disk storage. ApsaraDB Redis offers data read-write capabilities at high speeds by retrieving data in-memory caches. It also ensures data persistence using both memory storage and hard disk storage mode. ApsaraDB Redis supports advanced data structures like session, leaderboard, and tracking that are not possible with ordinary databases. ApsaraDB Redis also offers an enhanced version called "Tair". Since 2009, Tair has been officially handling data caching scenarios for Alibaba Group and has shown outstanding performance in scenarios like Double 11 Shopping Festival.

KeyDB is fully compatible with Redis modules API and protocol. You can easily drop in KeyDB to maintain compatibility with existing clients, scripts, and configurations. Multi-Master mode distributes a single replicated dataset across multiple nodes to support both read and writing operations. Nodes can be replicated across regions to provide submillisecond latency to local clients. Cluster mode allows unlimited read/write scaling by splitting the data across multiple shards. This allows unlimited scaling and supports high availability via replica nodes. KeyDB provides new community-driven commands that allow you to do more with data. ModJS module allows you to create your own JavaScript commands and functionality. ModJS allows you to write Javascript functions that can be called directly from KeyBD. The left example shows a Javascript function that would be loaded along with the module. It can then be called from your client.
