Currently the way to get documents from Domino via GRPC/Proton is to perform a DQL Query.
But DQL does not allow for document sorting, so if - for ex - I want to get the 5 first documents based on a field sorting, I need to get all the documents (eventually multiple paged DQLQuery via readDocuments + start method), then sort then get the 5 first.
On our test app, it's a performance real bottleneck as soon as we have real life document numbers in our apps.
We would like QueryProcessor (that allow collection sorting) and / or view navigation methods to be exposed so we can easily get the first n-th document or queries like that. Then we can optimise our queries and the dialog between our client app (java bindings) and domino server
