Redis-to-Valkey Savings and Performance Calculator

The main advantages of migrating to Valkey include potential cost savings, improved performance, and freedom from vendor lock-in. Because Valkey is open source, there are no licensing fees, which can lead to significant savings, especially in large-scale deployments. Performance can also be enhanced due to Valkey’s implementation of multi-threaded I/O, which can better utilize modern multi-core processors for increased throughput and lower latency.

Yes and no. Valkey is designed to be a drop-in replacement for Redis 7.2.4. This means that for this version and earlier, you can migrate to Valkey with minimal changes to your application code. This is not true for later versions of Redis.

Valkey has introduced significant enhancements to its threading model, particularly with improved multi-threaded I/O. Benchmarks have shown that this can lead to substantially higher throughput and lower p99 latencies for both read and write operations compared to Redis, especially under heavy loads. This allows for better utilization of modern hardware.

While migration can be straightforward in simple deployments, production environments—especially those with clustering, high availability requirements, or strict SLAs—often introduce complexity. Options include performing a physical migration by copying the latest on-disk snapshot from Redis to Valkey, or establishing replication between Redis and Valkey to ensure a controlled cutover. In clustered setups, you can add Valkey nodes as replicas within an existing Redis cluster and promote them to primaries, but this requires careful orchestration to avoid downtime or data loss. Percona’s migration experts provide hands-on guidance, validation, and rollback planning to help you execute migrations with confidence, ensuring performance, stability, and minimal disruption to your workloads.

Percona offers comprehensive, enterprise-grade support for Valkey, designed to meet the needs of mission-critical workloads. Our services cover everything from architecture reviews, performance tuning, and high availability planning to ongoing 24×7 support and proactive issue prevention. We also provide specialized migration assistance for organizations moving from Redis or other key-value stores to Valkey, ensuring a seamless transition with minimal risk. With decades of experience supporting open source data stores in complex, large-scale environments, Percona delivers the operational stability, expertise, and responsiveness enterprises require to keep Valkey running at peak performance.

While Valkey started as a fork of Redis 7.2.4, the two projects are now on separate development paths. Over time, it is expected that their feature sets will diverge. However, the core functionalities are likely to remain similar for the foreseeable future, and the Valkey community is focused on continued innovation and performance improvements.
