How to get ETL Horribly Wrong

ETL ( Extract, transform, load) doesn't have to be like a spell on hell. To make a success of ETL systems, you need the freedom and ability to make graceful U-turns when you detect a mistake in architecture or configuration: to fix the root problem rather than to merely tackle the symptoms. Feodor lists the eight most common root causes of failure in ETL systems, and how to fix them.  Read more...

The ETL from Hell - Diagnosing Batch System Performance Issues

Too often, the batch systems that underlie a lot of database processing just grow without conscious design. When runs start to extend beyond their allotted time, and tuning no longer solves the problem, it is often discovered that batches are run in series, with draconian error handling. It is time to impose some rational design, and Nigel is a seasoned healer of batch processes.  Read more...

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.  Read more...
