Dedicated clusters start around $200/month for production workloads. The database automatically handles distribution, replication, and failover across regions with serializable isolation guarantees. Vector search (preview) enables pgvector-compatible similarity search in distributed environment, unique capability for globally distributed AI applications. Multi-region abstractions (REGIONAL BY ROW, GLOBAL tables) enable latency-optimized data placement. Change Data Capture (CDC) enables real-time streaming to Kafka, webhooks, or cloud storage. The PostgreSQL wire protocol ensures compatibility with existing tools and libraries. Best suited for applications requiring both global distribution and strong consistency.
