Overview of this book

SQL Server Integration Services is a tool that facilitates data extraction, consolidation, and loading options (ETL), SQL Server coding enhancements, data warehousing, and customizations. With the help of the recipes in this book, you’ll gain complete hands-on experience of SSIS 2017 as well as the 2016 new features, design and development improvements including SCD, Tuning, and Customizations. At the start, you’ll learn to install and set up SSIS as well other SQL Server resources to make optimal use of this Business Intelligence tools. We’ll begin by taking you through the new features in SSIS 2016/2017 and implementing the necessary features to get a modern scalable ETL solution that fits the modern data warehouse. Through the course of chapters, you will learn how to design and build SSIS data warehouses packages using SQL Server Data Tools. Additionally, you’ll learn to develop SSIS packages designed to maintain a data warehouse using the Data Flow and other control flow tasks. You’ll also be demonstrated many recipes on cleansing data and how to get the end result after applying different transformations. Some real-world scenarios that you might face are also covered and how to handle various issues that you might face when designing your packages. At the end of this book, you’ll get to know all the key concepts to perform data integration and transformation. You’ll have explored on-premises Big Data integration processes to create a classic data warehouse, and will know how to extend the toolbox with custom tasks and transforms.

Using the lookup cache


The Lookup Transformation can use two different connection types: the OLE DB connection, which requires the reference data to be stored in a data store that can be accessed by the OLE DB data provider, or a Cache connection that requires thee data to be available in an SSIS cache object.

In essence, there are three different modes of operation (depending on how the reference data is made available):

  • In full cache mode, the reference data needs to be loaded completely into memory (cached) before the transformation can be used. Data is either loaded automatically (when an OLE DB connection is used to retrieve the lookup set), or needs to be loaded before the data flow, in which the lookup set is needed, and starts executing (when the cache connection is used to access the reference set).
  • With partial cache, the reference data is loaded into memory at run time, while the pipeline rows are being processed, and the execution engine determines automatically (based on the reference...
