LGTM 🎉 . Since this is a query and not state breaking can we merge before 0.43 RC? or should we block @AmauryM @robert-zaremba ?

OK to include this in 0.43. We can do a quick manual test once this is merged.

@AmauryM @aaronc can you follow up in #9393 (comment)? I'd like to know how to proceed with this PR.

I'm personally fine to merge this PR as-is, include it in 0.43, though I think adding #9533 (comment) is useful.

If we add another index as per #9393, it's state breaking so would need to wait the next release. I would do that in a follow-up PR.

I'd be happy to tackle the reverse index issue after this is merged.

yeah I think we need to have an index to avoid unmarshaling and doing this step
