Description
Add Milvus as a vector database option for knowledge base RAG workflows, following the existing Spanner integration pattern.
Motivation
ADK currently supports Vertex AI RAG, LlamaIndex, and Spanner for vector-based retrieval. Milvus is a widely adopted open-source vector database purpose-built for AI applications. Adding Milvus support would give developers a lightweight, self-hosted (or cloud-managed via Zilliz) alternative for building RAG agents.
Proposed Solution
MilvusVectorStore: Utility class for collection setup, data ingestion, and similarity search.MilvusToolset: BaseToolset implementation exposing a similarity_search tool to LLM agents.MilvusToolSettings / MilvusVectorStoreSettings: Pydantic configuration classes.- Users provide their own embedding function (e.g., Google GenAI
gemini-embedding-001).
pymilvus>=2.5.0 as an optional dependency (google-adk[milvus]).
