Elastifile Architecture – Metadata with Ezra Hoch

Ezra Hoch, Chief Architect, reviews how Elastifile handles metadata within their file system solution. Instead of making metadata a bottleneck of overall performance, especially for numerous smaller file sizes, Elastifile uses a consistency layering approach to get reliable performance at scale. At the lowest level this is governed by a configuration database, which is built on by an in-memory ownership repository, and the actual metadata handling. Any errors in the top most layer has failover to the one below it, which allows for consistent operations and at the base level, is resilient to substantial node and power failures.
