Indexes for approximate nearest neighbourhood (ANN) search (Annoy, USearch) can currently be build on columns of type Array(Float32) or Tuple(Float32[, Float32[, ...]]). In practice, only Arrays are relevant which makes sense as arrays store high-dimensional embeddings consecutively and the additional flexibility of different data types in a tuple is not needed. Therefore, removing support for ANN indexes over tuple columns to simplify the code, tests and docs. |
