Defer and stream directives

[Ericnr]

Is it planned to support these directives?

[hoangvvo]

benzene relies on graphql-jit which currently does not support those directives. So there needs to be a PR to implement it there.

Another option would be to add a way to fallback to graphql-js (which already has it under experiment branch I think?) for queries with defer and stream. This way we can still take advantage of the performance for non-stream queries while supporting defer+stream directives (or any future directives that graphql-jit do not support for the time being)

I have not look at graphql-js implementation in detail but they might be similar to the use of async interator in graphql subscription, which is being implemented in this PR. If that is the case, it might not be too hard to implement it also in graphql-js after merging the mentioned subscription implementation

Cool! Feel free to close this issue or use it to track the development of these directives
