When should I avoid milvus?

If your project does not require vector similarity search or approximate nearest neighbor search capabilities. When the project is not cloud-native and does not benefit from cloud-native optimizations. If the project's requirements are better met by a non-vector database or a different type of database. When the specific indexing techniques and performance characteristics of Milvus do not align with your project's needs.

When should I avoid RediSearch?

With an application that exclusively needs basic caching features without advanced querying, as RediSearch adds overhead not justified in such cases. In environments where the storage and querying of unstructured data is minimal to non-existent, making full-text search capabilities redundant. For teams or applications that prefer or require a cloud-managed solution for vector similarity searches without wanting to manage Redis. If your project uses another database system not based on Redis and you're looking for a tightly integrated query engine.
