As AI technologies like large language models (LLMs) and Retrieval Augmented Generation (RAG) continue to evolve, the demand for flexible and efficient data infrastructure is growing. Metadata lakes are emerging as a key solution in this regard, offering a unified approach to data management by storing metadata from various sources in an organization. Metadata provides context and understanding of the stored data, including data source, quality, lineage, ownership, content, structure, and context. Metadata lakes can assist with RAG development, model registration, AI governance, and implementing advanced analytics. By providing a unified plane for data operations, metadata lakes empower teams to maintain observability in metadata analysis, ensure smooth transitions between different cloud environments and data sources like the Milvus vector database, and uphold governance frameworks seamlessly. As AI technologies advance, metadata lakes will play a key role in supporting next-generation AI/ML applications.
