Incremental Load Design Patterns By Tim Mitchell

Incremental Load Design Patterns By Tim Mitchell June 14, 2017 at 1 Pm CDT Incremental Load Design Patterns When building extraction, transformation, and load (ETL) processes, one of the most common requirements is to process only new or changed data. This incremental load design significantly improves the performance of the ETL process by dealing only with a subset of the data during each load. Choosing the correct change detection mechanism for each incremental load process is critical. From change data capture to change tracking in SQL Server, to the slowly changing dimension wizard and other native tools in SSIS, there are many ways to detect and process incremental changes. In this session, we will review the common decision points surrounding incrementally loading data, and will walk through methods for incremental processing in SQL Server. Among the topics of discussion:  “Why not just do a full load?”  A survey of the various methods of change detection in SQL Server  Common incremental load design patterns for sources and destinations  Performance considerations for large incremental loads This session is ideal for those with some experience performing ETL operations in SQL Server and SSIS, but can be useful as an overview for others who want to gain a general understanding of incremental load patterns.
