Below are the minimum and recommended requirements:
| Component | Minimum Specs | Recommended Specs |
|---|---|---|
| OS | Ubuntu 20.04+, CentOS 7, macOS (dev only) | Ubuntu 22.04 LTS |
| CPU | 4 cores | 8–16 cores (for indexing/searching large datasets) |
| RAM | 8 GB | 32 GB+ for general workloads, 64 GB+ for large-scale deployments or high QPS |
| Storage | 100 GB SSD | 1 TB+ NVMe SSD for performance and durability |
| GPU | Not required to run Milvus itself | Recommended GPUs:NVIDIA RTX A6000, A100, or A40 for batch embedding, CUDA toolkit if using GPU-accelerated Faiss indexing |
| Docker | Docker 20.10+ and Docker Compose required | Latest stable |
| Others | Docker Compose, Python, Open ports: 19530 (Milvus), 9091 (metrics), etc. | High-speed internal LAN for multi-node setups, Monitoring + object storage |
| Feature / Capability | Milvus | ChromaDB | Qdrant |
|---|---|---|---|
| Overview | High-performance vector DB optimized for scale and cloud-native deployments | Lightweight vector DB focused on simplicity and integration with LLM apps | Scalable vector search engine with rich filtering, payload support |
| Main Use Case | Production-grade vector search at scale | Prototyping, local LLM apps, embeddings | LLM RAG apps, hybrid filtering, real-time search |
| Performance | Very fast indexing & search, supports HNSW, IVF, and GPU-accelerated Faiss | Good for small to mid-scale apps | Fast, low-latency search with filtering and quantization |
| Data Storage | On-disk + in-memory hybrid (RocksDB or S3 backend) | In-memory (optional persistence via duckdb) | On-disk, SSD-optimized |
| Scalability | Excellent – supports cluster mode (via etcd, Pulsar, MinIO) | Limited – mostly local or dev use | Good – horizontal scaling and clustering support |
| Vector Index Types | IVF, HNSW, GPU-accelerated Faiss, DiskANN | Only HNSW (simplified options) | HNSW, PQ, SQ, Flat, Binary support |
| Filtering Support | Yes (limited in early versions, now improving) | Basic (few metadata filters) | Rich filtering (metadata + payload) |
| Hybrid Search (text + vector) | Basic support with reranking logic | None (unless you build it) | Excellent (filtering + scoring hybrid) |
| Language Bindings | Python, Java, Go, REST, C++ | Python (built for LangChain, LlamaIndex) | Python, REST, gRPC, TypeScript |
| Deployment Options | Docker, K8s, Bare Metal, Cloud | Local (pip install chromadb) | Docker, K8s, Cloud |
| GPU Support | ✅ Yes (optional Faiss GPU acceleration) | ❌ No | ❌ No (CPU only) |
| Open Source License | Apache 2.0 | Apache 2.0 | Apache 2.0 |
| Monitoring & Observability | Prometheus/Grafana integration | No native support | Prometheus-compatible metrics |
| Ease of Use | Medium (complex setup for cluster) | Very easy (pip install, Python-native) | Easy with Docker/K8s |
| Community & Ecosystem | Large (by Zilliz, backed by LF AI) | Growing, LangChain/LlamaIndex focus | Active, with REST/gRPC SDKs & docs |
