Featured Presentation

Temporal Table and a stateless ETL

Speaker: Daren Child

Summary: Often ETL’s are designed in a quick adhoc fashion, not a lot of thought or design is put into the ETL other than successfully completing a data flow. This ability to quickly develop ETL’s often leaves a ETL less robust and the ETL normally is sensitive to schedule, interruption, or unforeseen failure. A stateless ETL is an ETL that can be ran any number of times, never have to be cleaned up and always pick up the correct set of records. If a stateless ETL fails midstream, the next scheduled run will complete the ETL. This can be easily accomplished using patterns with SSIS. Additionally, the new Temporal Table feature in SQL Server 2016 allows one to easily detect change, and drive a data flow in a stateless manner. This demonstration will be to showcase the new features of Temporal Table and to show the advantages of a stateless ETL.

Call for Speakers

Peter Palka is trying to put together a 6 month calendar of speakers and topics. Peter would like to start having two presentations per meeting. One topic could be a short 15 minute presentation and then the other could be a 60-90 minute topic. 

 If you have done something you think is noteworthy that others could benefit from, Peter would like to hear from you. He is willing to help you turn any ideas you have into a presentation. OASSUG is a user group, provided and supported by local area SQL Server users.

  Remember you don’t have to do a full-blown 90 minute presentation; even just a short presentation would be a great way to support our local SQL Server user group.
