Scaling Gerrit - JVM Tuning, Upgrades, and Architecture Enhancements from the SRE Perspective

Learn practical engineering strategies for scaling Gerrit to handle enterprise workloads through this 28-minute conference talk from the OpenInfra Foundation. Discover how Qualcomm successfully implemented Java 21 with ZGC heap tuning to reduce garbage collection pause times, upgraded to Gerrit version 3.10 for enhanced performance and security, and resolved storage bottlenecks by distributing load across replicated nodes. Explore caching optimizations on replicas that accelerate read-heavy operations and gain insights from real-world transformation experiences. Master JVM deep dive techniques, Gerrit upgrade methodologies, and storage architecture improvements designed to achieve operational excellence in large-scale development environments.
