Milvus Integration for Guest Memory

Design a memory system for your agent using Milvus to store and retrieve guest profiles and past interaction history. Create a Python component that can embed guest data (e.g., preferences, past requests) and store it in Milvus. Implement a retrieval function that the agent can call (as a custom tool) to query Milvus for relevant guest information based on the current conversation context. Demonstrate how the agent uses this tool to personalize responses.
