PROFILE
Rahul Sharma
Worked on the apache/parquet-java and apache/arrow-rs repositories, focusing on testing efficiency and data correctness in Java and Rust environments. In parquet-java, introduced parameterized tests for ParquetRewriterTests, enabling dynamic configuration of records and rows per page, which reduced memory usage and test runtime while improving CI reliability. In arrow-rs, addressed a bug in the Parquet module’s INT96 min/max statistics calculation, adding an end-to-end round-trip test to ensure accuracy. Leveraged skills in data engineering, performance optimization, and testing to enhance both test coverage and data reliability, contributing to more robust analytics and streamlined release processes across both projects.

Mar 1, 2025March 2025 monthly summary focusing on key accomplishments in the Apache Parquet Java project. Delivered a significant testing efficiency improvement for ParquetRewriterTests by introducing parameterized test cases across different numbers of records and rows per page, along with a refactor of test setup to dynamically configure these parameters. This optimization reduces memory usage and test runtime, enabling faster feedback cycles and more reliable releases.
