Worked on the opensearch-project/k-NN repository to enhance the Lucene Scalar Quantizer, focusing on improving performance, configurability, and maintainability. Introduced 1-bit compression support and enabled user-specified encoders, allowing for flexible compression levels without automatic bit resolution. The technical approach involved streamlining the quantization path, reducing memory usage, and clarifying component naming for downstream integration. Expanded integration and unit testing ensured that encoder behavior aligned with user configurations and maintained reliability. All changes were implemented in Java, leveraging Lucene for backend development and data compression. The work removed redundant components, resulting in a more maintainable and consistent codebase.
