1. Is this request related to a challenge you're experiencing? Tell me about your story.

The solution must support the ability to add custom metadata when embedding knowledge into the vector database via Dify or its APIs.

• Currently, there is no way to attach metadata to embedded data, limiting search, filtering, and contextualization capabilities.
• Similar to other vector databases like Redis and Weaviate, we require the ability to add custom metadata fields, such as categories, document types, or other relevant tags.
• This metadata should be queryable and retrievable to enhance search and retrieval functionality.
