Consolidating Storage Backend at Scale with Tectonic Filesystem

Tectonic is Facebook’s exabyte-scale, datacenter-wide distributed filesystem. Prior to Tectonic, Facebook’s storage infrastructure consisted of a constellation of smaller, specialized storage systems. Blob storage was spread across Haystack and f4. Data warehouse was spread across many HDFS instances. Tectonic consolidates the service-specific systems into general multitenant filesystem instances that achieve performance comparable to the specialized systems. This talk presents motivations behind building Tectonic, high-level architecture of Tectonic, and lessons from rolling out Tectonic into production.
