Abstract
Aspects of the disclosure are directed to managing files in data lakehouses using rewrite-free loading. Rewrite-free loading includes keeping track of information from data files that could be missing when imported to the data lakehouses without having to perform full-copy loading. Rewrite-free loading can store this information in table metadata or augment headers and/or footers of the data files with this information when importing to a data lakehouse. Rewrite-free loading allows for more accurate management of data lakehouses with lower computational costs.
