> [CEP-30|https://cwiki.apache.org/confluence/display/CASSANDRA/CEP-30%3A+Approximate+Nearest+Neighbor%28ANN%29+Vector+Search+via+Storage-Attached+Indexes]
> # Implement approximate nearest neighbor (ANN) vector search capability in
> Apache Cassandra using storage-attached indexes (SAI).
> # Support a vector of float32 embeddings as a new CQL type.
> # Add ANN search to work with normal Cassandra data flow (insertion,
> updating, and deleting rows). The implementation should support adding a new
> vector in log(N) time, and ANN queries in M log(N) time where N is the number
> of vectors and M is the number of sstables.
> # Compose with other SAI predicates.
> # Scatter/gather across replicas, combining topK from each to get global
> topK.
