Choose milvus if…
- milvus is primarily Go; cuvs is Cuda.
- Pricing: Milvus is open-source under Apache-2.0 license..
- Requirements: Min 4 GB RAM.
- Tags unique to milvus: distributed, cloud-native, embedding-database, embedding-store.
- Use Milvus when you need to perform efficient vector similarity searches specifically leveraging the Approximate Nearest Neighbor (ANN) algorithm.
When NOT to use milvus
- Avoid Milvus when you need immediate native compatibility with FAISS or similar standalone libraries as it has distinct features tailored to its own ecosystem.
- Do not use Milvus if your application strictly requires real-time indexing updates and low-latency search operations, since optimizing for ANN search may introduce trade-offs in these areas.
Choose cuvs if…
- cuvs is primarily Cuda; milvus is Go.
- Tags unique to cuvs: clustering, sparse, gpu, cuda.
- - When you need high-performance vector operations leveraging the parallel processing power of GPUs, specifically with CUDA.
When NOT to use cuvs
- - For environments where GPU resources are limited or unavailable because cuVS heavily relies on CUDA's capabilities for performance gains.
- - When you prioritize portability across different hardware, as cuVS being tied to CUDA means it may not be optimal on non-NVIDIA GPUs or CPU-only systems.
