KeyDB Speeds Up The User Experience For Any Project
Whether you're starting small or serving millions of users,
KeyDB enables you to provide a fast and reliable experience to your users
High Throughput
KeyDB is meant to handle heavy workloads with a single node benchmarking at over 1 million ops/sec. KeyDB is a multithreaded database and will outperform Redis on a per-node basis.
Low Latency
By keeping data in-memory, KeyDB can serve up data with submillisecond latencies.
A Variety of Data Structures
A variety of data structures are supported such as strings, hashes, lists, sets, sorted sets, bitmaps, hyperloglogs, geospatial indexes, and streams
Multiple Persistence Options
Periodically dump the dataset to disk or by appending each command to a disk-based log. Durability preferences for RDB and AOF persistence are configurable
Scalable to Any Workload
While a single KeyDB node scales vertically, you can scale horizonally through active-replication, or cluster-mode (sharded dataset) to meet much larger workloads.
High Availability
High availability setups are simple with active-replica nodes that do not require sentinel nodes for failover. HA setups are also available for sharded cluster-mode configurations with automatic failover
Open Source Features That Set Us Apart
While KeyDB maintains parity with the vanilla Redis feature set,
it offers some major open source advancements
MVCC Non-Blocking Architecture
With an MVCC implementation at the underlying architecture, KeyDB can query individual snapshots of the database, avoiding otherwise blocking calls such as SCAN and KEYS. Such queries can now be called concurrently at scale without reducing overall performance of existing workloads
Cross Region Multi-Master Support
Run multiple master nodes replicated asynchronously to eachother with a last write wins methodology. This enables support of a single replicated dataset where all nodes are masters with no need for sentinel monitoring nodes for failover.
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.
TLS Encryption
KeyDB offers TLS support that can operate at 7x the throughput of Redis + TLS
While TLS encryption adds additional CPU overhead, KeyDB’s multithreaded architecture enables more worker threads to prevent any decline in performance.
ModJS
Create your own commands with KeyDB’s open source javascript module. Built on the powerful V8 JIT engine, ModJS is faster than LUA and supports many node.js modules to offer extensive library support for common tasks
More in Store...
Exciting features are on their way! FLASH storage is scheduled for release in Q3, we are also working on JSON support, multi-tenant support, and RAFT. Check out our roadmap for details
