Developed and delivered the DiskANN Search Module for the infiniflow/infinity repository, focusing on scalable approximate nearest neighbor search over large datasets. The work centered on implementing disk-based indexing and search functionality in C++, leveraging advanced algorithms and data structures to enable efficient on-disk ANN search. Key technical contributions included PQ table generation, data compression, and a cached beam search strategy to optimize performance. Reliability and maintainability were enhanced through comprehensive unit testing and a refactor of default values. This module prepared the codebase for large-scale vector search, emphasizing performance optimization and robust, test-driven engineering practices throughout the development process.
