How to find top N similar rows given a specific row/id? We’ll demonstrate how Azure Data Factory can enable a new UI-driven ETL design paradigm on top of Azure Databricks for building scaled-out data transformation pipelines. Every major big data analytics project requires collecting data from disparate sources, getting it into the right format and then loading it back into the analytics software. This process reduces the need for you to adjust and run the repetitive transformation for each specific input. Heudecker said, "This is more than a data warehouse, this is a data warehouse with analytics." ETL provides a deep historical context and a consolidated view for the business by surfacing the metadata. Many companies are built from acquisition and will not get rid of separate data warehouses.
