EXTERNAL_QUERY SQL pushdown optimizes data retrieval from external sources like Cloud SQL or Cloud Spanner databases. Transferring less data reduces execution time and cost. SQL pushdown encompasses both column pruning (SELECT clauses) and filter pushdowns (WHERE clauses). SQL pushdown applies to SELECT * FROM T queries, a significant percentage of all federated queries. Not all data types are supported for filter pushdowns. This feature is generally available (GA).
