Module workflow_core::lookup

LookupHandler provides ability to queue multiple async requests for the same key into a group of futures that resolve upon request completion.

This functionality is useful when a client may be making multiple requests for data that is not available and may need to be fetched over a transport that may take time (such as network I/O). Each async request for the same key will get queued into a set of futures all of which will resolve once the initial request is resolved.
