Redis vs. Dragonfly Scalability and Performance

Redis vs. Dragonfly Scalability and Performance

A thorough benchmark comparison of throughput, latency, and memory utilization between Redis and Dragonfly.

Extreme Performance

Dragonfly delivers 25x the performance of legacy software

The power of modern cloud hardware can never be realized with legacy software. Dragonfly is optimized for modern cloud computing, delivering 25x more throughput and 12x lower snapshotting latency when compared to legacy in-memory data stores like Redis, making it easy to deliver the real-time experience your customers expect.

More QPS than Redis


Faster snapshotting than Redis

Reliable By Design

Dragonfly delivers the reliability your customers expect

Efficient Snapshotting

Dragonfly makes extremely efficient use of memory (i.e., no spike in usage during snapshotting), dramatically reducing the risk of out-of-memory outages.

High Availability

Dragonfly natively supports an eventually consistent primary-replica model to achieve high availability. If an outage on the primary occurs, Dragonfly will automatically failover to the replica and promote it as the primary.

Vertical Scaling

Dragonfly is a simple system with a single instance for workloads up to 1TB. This eliminates the fragility inherent to distributed clusters and dramatically improves the reliability of the system.

Effortless Scale

Dragonfly scales effortlessly, even for the heaviest workloads

Dragonfly is architected to deliver the scalability that modern data workloads require. Say goodbye to complex multi-node environments with endless configuration options and infinite points of failure. Dragonfly can effortlessly scale up to handle over 1TB of data and 4 million QPS on a single node, with a simple primary-replica pattern for high availability.

1 TB

In-memory datasets on a single instance


Less memory usage

Unparalleled Efficiency

30-60% better memory utilization than Redis

Dragonfly delivers a minimum 30% increase in memory efficiency over legacy Redis instances due to its unique hashtable design. The non-contending, multi-threaded architecture allows for more efficient utilization of CPU and memory, resulting in less hardware being required for the same workloads. Dragonfly also eliminates the increased memory usage during the snapshot phase that is typical with Redis, further reducing costs.
