Based on the current design, query settings will only be supported for queries handled by the multiplanner for both Classic and Nebari engines.

Once Bonsai becomes available it would be great to make them support query settings as well.

The tasks would be:

• Support the "v3" engine hint. Currently v1 (Classic + Multiplanner) and v2 (Nebari + Multiplanner) are planned to be supported.
• Support index hints specified using persistent query settings in Bonsai.
• Ensure that the ‘querySettings’ field in the explain output is present and accurate in CQF explain
