Managed vector peer for Cassandra estates / huge write scale. Depot defaults remain Supabase pgvector / Qdrant / Pinecone. Medium until RU card is as crisp as Pinecone. Strengths: Cassandra-backed vector + JSON for huge scale; Multi-cloud marketplace distribution; Good when you already standardize on DataStax.
Lock-in risk: higher = more lock-in (worse). Overall already inverts this dimension.
