Enable a client Implement the ability to retrieve a fetch collection record (with a given UUID) records from its home cluster, even if the remote clusters in arvados-controller h3. Fetching collection is hosted on a different flow # Home cluster in a federation. This issue covers the aaaaa # Client sends request for collection UUID ccccc-* to arvados-controller changes required for basic functionality. * proxy "get collection" requests with foreign UUIDs cluster aaaaa # arvados-controller sends request for collection by UUID (with salted token) to federated cluster ccccc (this should reuse as much as possible the appropriate remote cluster (similar to code from #13493) * alter # ccccc returns result # arvados-controller modifies the signature hints in the returned signatures to indicate they are "remote" signatures # return record so keepstore will be able to get client with modified signatures Question: What is the data from the remote format for a "remote" signature? Probably something like regular signature + cluster (see [[Federated collections]] wiki) This issue does not include * cache optimizations * changes to keepstore (#13994) id.
