Google Cloud Spanner

What Google Cloud Spanner is

Google Cloud Spanner is a globally distributed database combining relational, graph, key-value, and search capabilities. It provides strong transactional consistency, with transactions described as Strong-ACID and ordered using TrueTime. Horizontal read and write scaling, automatic sharding, and geo-partitioning support distributed workloads. Search and graph features include Spanner Graph, vector search, and full-text search. A columnar engine supports ad hoc analytics on live data, and integration with BigQuery enables federated queries. Spanner Omni is a downloadable option for running on-premises, across clouds, or on a laptop. Client libraries are available for C++, C#, Go, Java, Node.js, PHP, Python, and Ruby. Google lists integrations including Cloud Run, Dataflow, Cloud Storage, Compute Engine, GKE, Gemini Enterprise Agent Platform, and Looker. Security features include encryption in transit and identity and access controls. A free trial instance is available for up to 90 days, but it is limited to 10 GB, has no SLA, and is not intended for production use. Compute pricing is listed hourly per 100 processing units per replica: $0.03 a month for Standard, $0.04 a month for Enterprise, and $0.06 a month for Enterprise Plus.
