Harsh Srivastava developed two features focused on data management and profiling within the apache/iceberg and datahub-project/datahub repositories. He implemented branch-aware rewrite_data_files in Apache Iceberg, enabling isolated data file operations on development branches without affecting the main snapshot, and ensured data integrity through targeted unit tests. In DataHub, he enhanced the Iceberg profiler by adding a sizeInBytes attribute, allowing for more accurate dataset profiling and improved cost accounting. His work leveraged Java, Python, and Apache Spark, with an emphasis on robust test coverage and cross-repository compatibility, reflecting a deep understanding of big data engineering and data profiling challenges.
