ValkeyConf 2026

Why should a 50GB database require 100GB of RAM just to take a backup or sync to a replica? Valkey’s Forkless Save & Sync capabilities decouple data persistence from the memory-intensive forking process, eliminating the memory spikes that lead to out-of-memory (OOM) issues. We will compare traditional fork-based persistence against the new forkless model, highlighting the impact on system resource utilization. Learn how Valkey helps you configure your clusters for true operational stability.

Forkless Save/Sync is one of the most anticipated features coming to Valkey. The talk at Unlocked/Seattle was well regarded. This talk will cover similar material, but will have increased focus on full-sync.

While fork/forkless is a fairly advanced topic, the concepts are introduced with suitable foundation such that beginners will be able to understand the concepts and impacts. The talk is designed to appeal to all audiences, while still capturing the attention of advanced engineers.

Note: I'm answering "no" to "presented this talk before" because I'll be changing some of the content. However, yes, most of it will come from my presentation at Unlocked/Seattle.

Are you sure your in-memory datastore is truly secured against unauthorized access, accidental key overrides, and data exposure in production?

Securing Valkey goes far beyond setting a single cluster password. As microservice architectures scale, developers must balance zero-trust isolation with low latency. In this talk, we bridge the gap between application code and Valkey security models. We will explore practical strategies for implementing granular Access Control Lists (ACLs), mutual TLS (mTLS) certificate mapping, and secure connection pooling without sacrificing execution speed.

We'll also dive into recent enterprise security enhancements across modern Valkey releases, including database-level ACL scoping (db=N), enterprise LDAP integration, and automated TLS certificate rotation. You'll walk away with actionable code patterns for multi-tenant key isolation, least-privilege command restrictions, and audit logging.

Whether you're building high-throughput microservices or managing sensitive cached datasets, this session equips you with the tools to build a robust defense-in-depth architecture.
Excited to share best practices and secure our Valkey applications together!
