* chore: Normalise name of Call expression to lowercase Simplifies matching functions in planner, as they are guaranteed to be lowercase. This also ensures compatibility with InfluxQL when generating column alias names, which are reflected in updated tests. * chore: Ensure aggregate functions fail gracefully. * feat: GROUP BY tag support * feat: Ensure schema-level metadata is propagated Requires: https://github.com/apache/arrow-rs/issues/3779 * chore: Add some tests to validate GROUP BY output * chore: Add clarifying comment * chore: Declare message in flight.proto The metadata is public API, so best practice is to encode this in a way that is most compatible for clients in other languages, and will also document the history of schema changes. Added tests to validate the metadata is encoded correctly. * chore: Placate linters * chore: Use correct column in test cases * chore: Add `is_projected` to the TagKeyColumn message `is_projected` is necessary to inform a client whether it should include the tag key is used exclusively for the group key (false) or also projected in the `SELECT` column list. * refactor: Move constants to `schema` crate per PR feedback * chore: rustfmt 🙄 * chore: Update docs for InfluxQlMetadata Co-authored-by: Andrew Lamb <alamb@influxdata.com> --------- Co-authored-by: Andrew Lamb <alamb@influxdata.com> |
