The Postgres Analytics Accelerator (PGAA) achieves its high performance by offloading analytical workloads to Seafowl and Apache Spark, a vectorized execution engine designed for massive scale. By understanding how PGAA selects execution paths, you can ensure your queries stay on the "fast path" for maximum acceleration.
