DuckDB analysis instance

When you run complex reporting or analytical queries on your RDS PostgreSQL instance, they can consume substantial resources and affect the performance and stability of your core business operations. To address this issue, RDS PostgreSQL introduces the DuckDB analysis instance. This instance handles analytical workloads. It uses a separate node to implement read/write splitting, isolating analytical processing (AP) workloads from online transaction processing (TP) workloads. This significantly improves the efficiency of complex analytical queries without impacting the performance of the primary instance.
