Why 2025 Is the Year to Move to Valkey 8.1 — And How We Did It in One Line

If you’re still running Redis in production (or haven’t yet upgraded to Valkey 8.1), 2025 is the year to make the leap. The Valkey project has matured, Amazon has made ElastiCache for Valkey 8.1 generally available, and the performance benefits are undeniable.

At Kedos Consulting, we run Badger Commerce, our high-throughput e-commerce platform. We migrated to Valkey last year and recently upgraded to Valkey 8.1 — and the process was so painless, it’s worth sharing as a model for how simple this move can be.

Why Valkey Now?

Valkey was forked from Redis in 2024 to keep the in-memory data store truly open source under the BSD license. In just a year, it has evolved quickly — delivering measurable gains:

41% faster SUNION operations
27% faster SDIFF operations
Improved memory efficiency thanks to a new hash table design
New features like native Bloom filters, enhanced observability (COMMANDLOG), and memory optimisations

In short: it’s faster, leaner, and ready for production — with all the Redis protocol compatibility you’d expect.

Our Experience: Badger Commerce

When we first moved from Redis to Valkey in 2024, the migration was nearly trivial. Now, in 2025, our upgrade to 8.1 was even easier. Here’s literally all we had to do:

# Change from:
image: valkey/valkey:<previous-version>-alpine

# To:
image: valkey/valkey:8.1-alpine

That’s it — a one-line change. No code rewrites, no client library upgrades, no change to monitoring or health checks. Our redis-cli ping probes passed immediately after rollout.

Within minutes, we were running on 8.1 and already seeing lower memory usage and faster responses in cache-heavy endpoints.

Why It’s So Simple

Valkey makes this easy because it:

Speaks the same protocol as Redis (same default port 6379)
Supports the same commands — existing code doesn’t break
Works with all Redis client libraries out of the box
Keeps operational tooling intact — including health checks and monitoring

For many teams, this will be a drop-in replacement that takes less time than a typical dependency upgrade.

What You Get in Return

The upgrade delivers immediate wins:

Faster queries: Our internal measurements mirrored AWS’s benchmark numbers, particularly on set operations (SUNION, SDIFF).
Lower infrastructure costs: The memory efficiency gains allowed us to run the same workload with smaller container sizes.
Better insights: The new observability features make it easier to trace slow queries and optimise workloads.

And with AWS offering managed Valkey 8.1 on ElastiCache, you get a fully supported, production-ready service that’s easy to scale.
