Fastload is a Teradata SQL feature for high-speed bulk loading, used for data acquisition and application phases.In MySQL, there is no direct alternative to Fastload, but loading from a CSV file, using MySQL Shell, or multi-row inserts can be utilized.For PostgreSQL, the COPY command, pg_bulkload extension, and parallel import with psql are recommended methods for efficient data loading.These alternatives can enhance query speed and performance in their respective SQL dialects.
