Description

Topics:

  • Listing and pagination
  • Need for multi-threaded S3 crawl over keys for speed
    • Prefix-based listings, with separators
    • Hash-type prefixes with known alphabet, uniform distribution
  • Possibly: Reassigning work; using markers to optimize if alphabet is not known
  • Tallying usage by mapreduce over keys that propagate usage up by folder
