What is AlloyDB?
Answer
AlloyDB is Google's fully managed, high-performance PostgreSQL-compatible database designed for demanding transactional and analytical workloads. It delivers up to 4x faster transactional performance and 100x faster analytical query performance than standard PostgreSQL. Key architectural innovations: Disaggregated storage: compute and storage are separate, enabling independent scaling. Google Columnar Engine: automatically identifies hot data and stores it in a columnar format in memory for analytical queries — no need for a separate DW. ML-based vacuum: predictive maintenance replaces manual VACUUM operations. High availability: 99.99% SLA with <60 second RPO. AlloyDB sits between Cloud SQL (standard PostgreSQL) and Cloud Spanner (globally distributed) — ideal for applications needing high performance without global distribution. It integrates with AlloyDB Omni for on-premises deployment.
