We all have tasks from time to time for bulk-loading external data into MySQL. What's the best way of doing this? That's the task I faced recently when I was asked to help benchmark a multi-terrabyte database. We had to find the most efficient method to reload test data repeatedly without taking days to do it each time. In my presentation, I'll show you several alternative methods for bulk data loading, and describe the practical steps to use them efficiently. I'll cover SQL scripts, the mysqlimport tool, MySQL Workbench import, the CSV storage engine, and the Memcached API. I'll also give MySQL tuning tips for data loading, and how to use multi-threaded clients.
