Description

Problem

I have a repetitive subscription witch leads to a repetitive query (if I'm not mistaken, since I need the QueryRef to execute the subscription QueryRef.subscribeToMore).

Finding solution

So I implemented apollo-link-batch-http in order to avoid 20 queries and it works great. But it's doing the same query with only uuid changing.

I thought that dataloader could help me out but it did not since they are separated queries (even if they are done in one call).

That 's why I thought that maybe it could be something that apollo-link-batch-http could to itself (or maybe another package like apollo-link-batch-merge-http).

It could merge queries that are using the same query.

What do you think?

Contributor guide

Research direction
Research how batched queries can be deduplicated based on identical query documents but different variables, and propose an extension to apollo link batch http.
