Optimizing Storage Efficiency for FB Video Processing
summary
Facebook standardizes on Source+MVE policy and implements a Video Lifecycle Manager that classifies videos as recent, hot, or cold and takes concrete actions: reduce semantic replicas of sources, purge ephemeral encodings, and (optionally) recompress sources. Applying replica reduction and purging yields about 45% measured storage savings since June and the team projects these lifecycle controls suppress 70% of Facebook Video’s 2021 projected storage growth, with a planned cost–benefit recommender to decide recompression.
