> Today IndexQuery always filters results to primary partitions via
> `IndexingQueryFilter`. This prevents using IndexQuery as a lower-level tool
> to scan a backup copy of a given partition (e.g. for diagnostics,
> verification, or experiments with backup-only reads).
> We should investigate and prototype a mode where, for an explicitly specified
> partition, IndexQuery can be directed to run on a backup replica instead of
> the primary.
