I wanted to bring some additional attention to some discussion occurring on a PR [1], specifically the proposal of how to construct output field names from queries that have multiple relations (that may have the same input field).
The documents are: * Document for output schema field name semantics with examples: [2] * Proposed change to @jorgecarleitao 's invariant doc [3] * Updated invariant doc with proposed changes applied [4] Please comment on the PR / in the docs if you are interested.
