Design: https://gist.github.com/klauspost/025c09b48ed4a1293c917cecfabdf21c Gist of improvements: * Cross-server caching and listing will use the same data across servers and requests. * Lists can be arbitrarily resumed at a constant speed. * Metadata for all files scanned is stored for streaming retrieval. * The existing bloom filters controlled by the crawler is used for validating caches. * Concurrent requests for the same data (or parts of it) will not spawn additional walkers. * Listing a subdirectory of an existing recursive cache will use the cache. * All listing operations are fully streamable so the number of objects in a bucket no longer dictates the amount of memory. * Listings can be handled by any server within the cluster. * Caches are cleaned up when out of date or superseded by a more recent one.
