問題文

The memo embeddings are 1024 dimensions of single-precision values. Capacity planning asks how the vector size affects storage, and whether switching to half-precision would hurt search quality. Which pair of statements matches the documented guidance?

選択肢

  1. Vector storage is independent of the page size because vectors are always stored outside the row, so only the query cost changes.
  2. Storage can be reduced by declaring the column as a sparse vector, which is the supported way to compress high dimension counts.
  3. A data page holds up to 8060 bytes, so a vector of that size limits how many vectors fit in one page; and reducing precision usually has minimal impact on the quality of similarity comparisons.
  4. Reducing precision must be avoided because embeddings are highly sensitive to small numerical changes.
