 Description   

Include a flag inside the slow query log to point out whether the multi-planning fallback mechanism was engaged due to inapplicable query settings. This flag should be present if and only if:

  • Query Settings are present for that shape.
  • The multi-planning fallback was engaged for that query. (The query settings failed to apply)
  • This shouldn't account for plan cached queries.
