ETL provides a deep historical context and a consolidated view for the business by surfacing the metadata. How to find top N similar rows given a specific row/id? Standard ETL processes like data quality, security, metadata management, and governance also remain relevant for data-driven organizations. Nowadays, ETL tools are very important to identify the simplified way of extraction, transformation and loading method. 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. Extremely important when different questions can be asked every day and the parameters are stored in systems outside of Hadoop, most likely, an enterprise scheduler like Autosys or control-M.
