Explore advanced metadata architecture design in this 50-minute conference talk that addresses the fundamental limitations of single-leader systems like GoogleFS and presents modern solutions for distributed file systems. Learn how traditional architectures with single active masters create bottlenecks in scalability, redundancy, and availability, then discover how contemporary systems like SaunaFS eliminate these constraints through distributed metadata management. Examine the implementation of concurrent, multi-threaded servers that replace single-leader models and understand how sharded, ACID-compliant transactional databases such as FoundationDB enable horizontal scalability and fault tolerance. Master the architectural patterns that support exabyte-scale operation within single namespaces while maintaining POSIX semantics and handling billions of small files. Gain insights into the technical challenges and strategic considerations involved in transitioning from centralized metadata servers to fully distributed metadata services, with practical examples of how reduced memory footprints and consistent performance under load are achieved through redundant metadata replicas and modern database technologies.
