### Description This PR adds the required IR for DB to DB joins, based on @paf31 and @0x777 's `feature/db-to-db` branch. To do so, it also refactors the IR to introduce a new type parameter, `r`, which is used to recursively constructs the `v` parameter of remote QueryDBs. When collecting remote joins, we replace `r` with `Const Void`, indicating at the type level that there cannot be any leftover remote join. Furthermore, this PR refactors IR.Select for readability, moves some code from IR.Root to IR.Select to avoid having to deal with circular dependencies, and makes it compile by adding `error` in all new cases in the execution pipeline. The diff doesn't make it clear, but most of Select.hs is actually unchanged. Declarations have just been reordered by topic, in the following order: - type declarations - instance declarations - type aliases - constructor functions - traverse functions https://github.com/hasura/graphql-engine-mono/pull/1580 Co-authored-by: Phil Freeman <630306+paf31@users.noreply.github.com> GitOrigin-RevId: bbdcb4119cec8bb3fc32f1294f91b8dea0728721 |
