Abstract
Whether a logical query plan to derive a target dataset from one or more source datasets is available is determined. Responsive to determining that the logical query plan is not available for the transformation code in the first programming language, relationships between the source columns of the one or more source datasets and the respective target columns of the target dataset are inferred. Target column metadata for a target column of the target dataset is generated. The target column metadata reflects the inferred relationships between the source columns of the one or more source datasets and the respective target columns. The target column metadata for the target column of the target dataset is stored.
