PROFILE
Xinli Shang
During August 2025, Shangx contributed to the apache/hudi repository by developing a configurable schema evolution control for binary copy operations within file stitching workflows. Leveraging Apache Spark, Parquet, and Scala, Shangx introduced the SparkStreamCopyClusteringPlanStrategy, enabling users to toggle schema evolution when clustering files with heterogeneous schemas. This approach improved the robustness of both streaming and batch data pipelines by allowing safer handling of schema variations and reducing manual remediation. The work included implementing Parquet-based row-group merging grouped by schema, which enhanced data quality and stitching performance. Shangx’s efforts focused on code refactoring, schema management, and pipeline stability.
