Systems and methods herein describe embodiments for handling a data drift. An example system accesses the data pipeline, which is comprised of a plurality of stages. For each stage of the plurality of stages in the data pipeline, the system identifies stage schema fields for processing data in the data pipeline and generates a set of stage schema fields comprising the identified stage schema fields in the stage. In response to detecting an origin stage, the system generates a set of pipeline schema fields, whereby the set of pipeline schema fields comprise a union of the generated sets of stage schema fields. The set of pipeline schema fields are then stored.
