Use a small sample of data to build and test your ETL project. All transformation steps must be complete without failure before the ETL performs the loading steps into GoodData. Do not attempt to build mechanisms that enable restarting of the graph with a partially processed dataset. A properly designed ETL system extracts data from the source systems, enforces data quality and consistency standards, confirms data so that separate sources can be used together, and finally delivers data in a presentation-ready format so that application developers can build applications and end users can make decisions.
