Description

Right now, the feature of automatic HTTP download in cwl-runner is effectively fulfilling this function for users (although it copies it into the local keepstore). Users would probably like it if it were expanded to also support copying s3:// URLs.

However, the big idea for this epic is on-demand retrieval from external storage -- we fetch the data from the external system on demand.

This involves:

  1. Going through each file of an external file system or bucket and hashing 64 MB byte ranges to get a block hash
  2. Keeping a database that maps the block hash to a URL and byte range
  3. Constructing a collection using these blocks with file/directory structure matching the external file system
  4. Creating a special keepstore volume type that uses the block hash database to fetch block contents from the external source on demand as if it were a normal keep service
