The database built for AI agents. OLTP runs the business. OLAP understands the business. Vector search provides the semantics. Most teams run all three on separate systems, connected by pipelines that introduce the exact latency and data inconsistency that makes agents unreliable in production. RegattaDB unifies all three in a single engine — so agents and applications read live state, execute transactions, and reason over context in one step. No pipelines. No replication lag. No fragmented stack. Benchmarked at 750,000 TPS at 98% efficiency, with OLTP and OLAP running concurrently on a 50-node cluster. 3–4x more workloads on the same hardware.
