Sivagnanam Arumugam developed a feature for the opensearch-project/data-prepper repository that enables parsing of JSON arrays within NDJSON input streams. By enhancing the NdjsonInputCodec in Java, Sivagnanam introduced array-aware parsing logic that detects and processes multiple arrays per input, allowing for more flexible data ingestion and reducing the need for manual preprocessing. The implementation included configurable handling of empty objects within arrays, improving the robustness of NDJSON pipelines. Sivagnanam validated the changes through targeted unit and integration tests, demonstrating strong skills in data processing, input/output handling, and JSON parsing while addressing a nuanced requirement in ingest workflows.
