Worked on the opensearch-project/data-prepper repository over two months, delivering two key features focused on data and log processing. Enhanced the add_entries processor to support parent field access during array iterations, introducing configurable evaluation rules and new options for more flexible nested data manipulation. Developed a multiline input codec that groups multi-line log events using configurable regex patterns, improving log parsing accuracy and pipeline observability. Both features were implemented in Java with configuration managed via YAML, leveraging skills in event processing, regex, and unit testing. The work improved data transformation fidelity and reduced manual post-processing, supporting more reliable downstream workflows.
