Summary: CEP-30 ANN Vector Search with SAI Key: CASSANDRA-18557 URL: https://issues.apache.org/jira/browse/CASSANDRA-18557 Project: Cassandra Issue Type: Epic Reporter: Jonathan Ellis [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. -- This message was sent by Atlassian Jira (v8.20.10#820010) --------------------------------------------------------------------- To unsubscribe, e-mail: commits-unsubscr...@cassandra.apache.org For additional commands, e-mail: commits-h...@cassandra.apache.org
