KeyDB is fast... Really fast!

Quickly becoming known as the fastest NoSQL database in the world, KeyDB clocks in at 5X faster than Redis (node vs node). KeyDB is a popular drop in Redis alternative that people flock to because it enables you to consolidate a lot of the complexities associated with Redis. KeyDB is multithreaded with the ability to use several storage mediums natively and scale vertically. The superior architecture is enabling KeyDB to become the bridge between cache layer and traditional databases offering performance and durability.

It's not what you would expect of an in memory database. Click any of the features below to find out more

  • FLASH thats Fast!

    KeyDB on FLASH reduces DRAM requirements drastically while operating at very fast speeds. Architected on RocksDB, KeyDB Professional on FLASH enables more throughput than Redis on DRAM! Take a look at what to expect from this feature and see benchmamrking results here

  • MVCC Support

    KeyDB Pro offers MVCC suppport which uses a lockless and wait free algorithm allowing concurrent operations enabling features such as non-blocking queries and forkless background saving. Transaction rollbacks will also be possible with this architecture.

  • Multithreaded

    KeyDB is fully multithreaded (not just IO) and as a result can use many machine cores to operate a single node. This is has enabled KeyDB to put our 5X the throughput of Redis. In order to get the same throughput with Redis, you would need to run a 7 node cluster on that same machine.

  • Active Replication

    This removes the need for sentinel nodes and enables writes to multiple syncd master nodes. Users like the simplicity of this feature, enabling easy integration with load balancers and reduces the number of moving parts to maintain high availability

  • Vertical & Horizontal Scaling

    KeyDBs multithreading enables you scale vertically, maximizing the resources of your machine before scaling out horizontally. It is a great option for those reaching the current limitations of their Redis instance.

  • Better EXPIRation

    KeyDB offers Subkey EXPIREs which enables expiration of members within a set. EXPIREs now also have near real time active deletion that removes major lags associated with old models of removing expired keys.

  • ACID Compliant

    KeyDB integrates MVCC support with durability options on persistent mediums. Transactions and querying are non blocking with atomicity guarentees. Transaction rollbacks coming soon and KeyDB datastructures in addition to the way we are able to persist data takes KeyDB to an ACID compliant standard

  • ARM Support

    KeyDB is built for ARM. KeyDB uses the available cores with its multithreaded architecture and is a very fast and lightweight database.

  • DRAM Speed Persistence

    (Coming Soon!) KeyDB has natively integrated Intel Optane DC Persistent Memory that enables complete persistence at 95% the speed of DRAM! No more writing to disk or worrying about your data. See the groundbreaking benchmarks KeyDB has been able to achieve and how this technology will transform how we use databases

  • Simple and Affordable

    You dont have to be a huge company to afford enterprise grade features with KeyDB. KeyDB Pro costs less than a cell phone bill and takes seconds to obtain a license key. You can try Pro free (1hr intervals) by enabling it on any of our binary release packages

  • Redis Compatible

    KeyDB is fully compatible with all Redis modules, API, and protocols. KeyDB works with your existing Redis clients and can be used as a drop in replacement.

  • Get There First
