May 2025 monthly summary for pathwaycom/pathway: Focused on refactoring to unify storage interfaces and improve maintainability, with backward-compatible changes that preserve public APIs for smooth upgrades. Key business-relevant outcomes: - Simplified architecture by refactoring VectorStore to inherit from DocumentStore, enabling code reuse across storage components and a unified interface for vector search and document handling. - Maintained backward compatibility by deprecating VectorStoreServer/VectorStoreClient in favor of DocumentStore counterparts while keeping the public API stable for existing users. - Enhanced indexing capabilities with a DefaultKnnFactory for creating Knn indexes, enabling scalable, consistent nearest-neighbor search. - Improved test fidelity and data pipelines by updating mock embedding functions to return NumPy arrays. Key achievements: - VectorStore refactor to inherit from DocumentStore with backward-compatible API (commit 5bcb0c71374a7de90a126e991f62aca521668124) - Deprecated old VectorStoreServer and VectorStoreClient in favor of DocumentStore wrappers - Added DefaultKnnFactory for Knn index creation - Updated mock embedding functions to return NumPy arrays
