What strategies can be employed to update a RAG system's knowledge base efficiently?

Efficiently updating a RAG system's knowledge base can involve several strategies: using delta updates to add or change portions of the database instead of a complete refresh, employing incremental indexing to only update affected data rather than rebuilding the entire index, and utilizing versioning to manage different states of information without significant downtime. Additionally, regular batch updates based on user queries or relevancy checks can help maintain data freshness.
