--------------------------------
> GraphQL results pagination
> --------------------------
>
> Key: SLING-10309
> URL: https://issues.apache.org/jira/browse/SLING-10309
> Project: Sling
> Issue Type: Improvement
> Components: GraphQL
> Affects Versions: GraphQL Core 0.0.8
> Reporter: Bertrand Delacretaz
> Assignee: Radu Cotescu
> Priority: Major
> Fix For: GraphQL Core 0.0.10
>
>
> We need a way to paginate results in the GraphQL Core module.
> We did some research with Radu around this, here are our initial findings:
> * Pagination should be based on cursors, not offsets. There's a good
> explanation of why at
> https://uxdesign.cc/why-facebook-says-cursor-pagination-is-the-greatest-d6b98d86b6c0
> * Pagination cursors should be opaque. They are often encoded in Base64 to
> express that, although that doesn't make much sense from a technical point of
> view (being easy to decode) but helps convey the "consider this thing as
> opaque" message.
> * https://relay.dev/graphql/connections.htm defines a commonly accepted way
> of expressing pagination in GraphQL results.
> * Automatically generating the "plurals" types, like Articles for an Article
> type, might be interesting and could include adding the required paging
> fields.
> * https://www.graphql-java-kickstart.com/tools/relay/ mentions the
> {{RelayConnectionFactory}} as a useful tool to generate the "standard" paging
> information
> * The {{SlingDataFetcherEnvironment}} needs to provide paging information
> such as the current cursor value and how many items are expected starting
> after it
> * The "Just the factoids" section of https://api.slack.com/docs/pagination
> nicely describes pagination in the Slack API, we should have something like
> that to clarify our "pagination pattern" and allow that pattern to be reused
> in other parts of Sling if needed.
