{"active transformations": "Active transformations in ETL are transformations that require real-time processing of data. They often involve complex calculations, conditional logic, or lookups to other tables. Active transformations can affect the performance of ETL jobs and should be used sparingly.","passive transformations": "Passive transformations, on the other hand, are simpler operations that do not require real-time processing. They include tasks like filtering, sorting, or aggregating data. Passive transformations are typically faster and more efficient than active transformations."
