1.7 hours ago  50 comments  0 votes  0 watches  benwtrent, github-actions[bot], kaivalnp, mccullocht, mikemccand, shubhamvishu, xande

    benwtrent 9.1 hours ago:  @shubhamvishu thank you a bunch for iterating on the API and the discussion here :)
    shubhamvishu 21.3 hours ago:  I pushed a new revision moving the complete rotation specific logic into the new vector format and ...

Also confirmed the earlier rotation benchmark numbers remain the same (so functionally all same)

    iverase 2.3 hours ago:  Changing approximated search to exact search under the hood just because of an update feels wrong.
    jimczi 2.5 hours ago:  I wonder if this is the right tradeoff for ANN-backed indices in general. Losing the ANN structure for the whole segment after a small vector update and falling back to ... Maybe this only really makes sense for flat indices where there is no ANN structure to invalidate? ...
