Choose milvus if…
- License: milvus is Apache-2.0, NornicDB is MIT.
- Milvus is designed to be self-hosted and can be deployed in a cloud-native environment.
- Pricing: Milvus is free to use under the Apache-2.0 license, but additional services or support may come at a cost..
- Requirements: Min 4 GB RAM; Requires Docker; Third-party dependencies must be installed before using Milvus.; Milvus is built with Go and requires a Go environment to run..
- Tags unique to milvus: anns, cloud-native, diskann, distributed.
- When you need a high-performance vector database that supports scalable approximate nearest neighbor search.
When NOT to use 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.
Choose NornicDB if…
- License: NornicDB is MIT, milvus is Apache-2.0.
- Tags unique to NornicDB: distributed-systems, gpu acceleration, graph-database, hnsw search.
- When you need both graph traversal capabilities and fast vector searches.
When NOT to use NornicDB
- If your application primarily requires traditional SQL database operations without the need for low-latency vector search or graph traversal.
- When you need a specialized tool, whether purely a graph database or a vector database, but not an integrated solution like NornicDB.
