1. Always allow vectorized indexing by means of (lazily) loading all indexed data into memory as a single chunk. This could potentially be very expensive for IO or memory in hard to predict ways.
2. Or to only allow vectorized indexing if a backend supports it directly. This ensures that when vectorized indexing works it works efficiently. Vectorized indexing is still possibly but you have to explicitly write I think I slightly prefer option (2) but I can see the merits in either decision. |
