We Loaded 1TB in 30 Minutes with SSIS, and So Can You
In February 2008, Microsoft announced a record-breaking data load using Microsoft® SQL Server® Integration Services (SSIS): 1 TB of data in less than 30 minutes. That data load, using SQL Server Integration Services, was 30% faster than the previous best time using a commercial ETL tool. This paper outlines what it took: the software, hardware, and configuration used. We will describe what we did to achieve that result, and offer suggestions for how to relate these techniques to typical scenarios. Even for customers who don't have needs quite like this benchmark, such efforts can teach a lot about getting optimal performance.
