Google Cloud announces general availability of native CQL (Cassandra Query Language) API support on Spanner, enabling existing Apache Cassandra applications to migrate with minimal code changes (often just one line). The post outlines key advantages over Cassandra including global ACID transactions, strong consistency, 99.999% availability, and lower TCO. It provides a migration roadmap covering workload optimization, retiring Cassandra sidecar tools (Reaper, Medusa, Elasticsearch, JanusGraph), and leveraging Spanner's multi-model capabilities including graph, full-text search, and vector search.
