Dragonfly, a multi-threaded Redis-compatible data store.

In short: Dragonfly is a modern in-memory data store, wire-compatible with Redis and Memcached, built on a multi-threaded shared-nothing architecture. It scales vertically across CPU cores. Whether it can consolidate a multi-node Redis workload depends on capacity, failure-domain, durability, and latency tests against the target environment.

We validate Redis and Memcached client compatibility, size the target from observed workload data, and define availability objectives, recovery behavior, and operational ownership in the engagement scope.

Full-spectrum Dragonfly engineering

From a sharded Redis cluster to a single Dragonfly node - we plan it, migrate it, and run it.

Performance Engineering

Tune Dragonfly's multi-threaded, shared-nothing engine to saturate every core - one node where a Redis cluster used to live.

Vertical Scaling

Right-size a single Dragonfly instance to replace a multi-node Redis cluster - no resharding, no client-side hashing.

High Availability

Primary/replica replication, snapshotting, and failover design for a resilient in-memory tier.

Redis/Memcached Migration

Drop-in, wire-compatible cutover from Redis or Memcached - your existing clients and commands keep working.

Cloud & Kubernetes

Deploy Dragonfly on Kubernetes with the operator, persistent snapshots, and rolling upgrades.

24/7 Managed DBA

Round-the-clock monitoring, memory-efficiency tuning, snapshot verification, and incident response.

Every core, working for you

Redis leaves most of your CPU idle. Dragonfly's shared-nothing engine spreads work across all cores in one process - higher throughput, lower memory, fewer nodes to operate.

Common questions about Dragonfly & Redis migration

What is Dragonfly?

Dragonfly is a modern in-memory data store that is wire-compatible with Redis and Memcached, built on a multi-threaded, shared-nothing architecture. It scales vertically across CPU cores, so a single node can replace a multi-node Redis cluster while using less memory.

Is Dragonfly a drop-in replacement for Redis?

For most workloads, yes. Dragonfly speaks the Redis (RESP) protocol, so existing clients and most commands work unchanged. We validate command coverage for your workload before cutover and run a dual-read verification window.

How does Dragonfly compare to a Redis Cluster?

Redis is single-threaded per process, so scaling means running many shards and managing client-side hashing/resharding. Dragonfly uses all cores in one process - you scale a single node vertically, eliminating cluster topology, resharding, and cross-slot limitations.

Do you offer 24/7 Dragonfly support?

Yes. Eligible support agreements provide round-the-clock monitoring, memory-efficiency tuning, snapshot verification, and incident response with severity-based targets stated in the signed contract.
