During April 2025, Healnet developed a Reservoir Sampling utility for streamed data in the Hardvan/Java repository. The work centered on implementing a static sampling method that efficiently selects k items from unbounded data streams, addressing the challenge of memory-efficient sampling for downstream analytics. Healnet applied expertise in Java, algorithm implementation, and data structures to ensure the solution integrated cleanly with the existing randomized module. Comprehensive unit tests were written to validate correctness, edge cases, and performance, reflecting a focus on robust engineering practices. The feature was delivered with attention to scalability and maintainability, though no bug fixes were recorded during this period.
