High-performance multi-model database with native AI/LLM integration
📚 Documentation · 🚀 Quick Start · ❓ FAQ · Release Notes · Roadmap
ThemisDB is an enterprise-grade, multi-model database engine that combines relational, graph, vector, document, geospatial, and time-series storage in a single system — with native AI/LLM integration built in. It is designed for workloads that require strong transactional guarantees, distributed operation, and advanced analytical capabilities alongside modern machine-learning workflows.
ThemisDB has comprehensive documentation for all 50 modules with production-ready standards:
Key capabilities at a glance:
| Capability | Details |
|---|---|
| Multi-model storage | Relational · Graph · Vector (HNSW/FAISS) · Document · Geospatial · Time-series |
| ACID transactions | MVCC, SSI, 2PC, SAGA orchestration, HLC-based global ordering |
| Distributed | Raft consensus, mTLS replication, consistent-hash sharding, auto-failover |
| AI/LLM native | Embedded LLM inference (llama.cpp, ONNX), RAG pipeline, prompt engineering, LoRA fine-tuning |
| Full-text search | BM25 + vector hybrid search (RRF), faceted, conversational, multi-modal |
| Observability | Prometheus metrics, OpenTelemetry tracing, PagerDuty/Slack alerting |
| Security | AES-256-GCM field encryption, RLS, Zero-Trust policy, eIDAS timestamping, HSM/Vault |
| Editions | MINIMAL · COMMUNITY · ENTERPRISE · MILITARY · HYPERSCALER |

ThemisDB is available in five editions, selected at CMake build time:
| Edition | Use case | Branch | Build flag |
|---|---|---|---|
| MINIMAL | Embedded / resource-constrained | main |
-DTHEMIS_EDITION=MINIMAL |
| COMMUNITY | Open-source, self-hosted | main |
-DTHEMIS_EDITION=COMMUNITY |
| ENTERPRISE | Commercial, SLA-backed | enterprise |
-DTHEMIS_EDITION=ENTERPRISE |
| MILITARY | Hardened / air-gapped | enterprise |
-DTHEMIS_EDITION=MILITARY |
| HYPERSCALER | Cloud/OEM, Kubernetes operator | hyperscaler |
-DTHEMIS_EDITION=HYPERSCALER |
Feature sets are nested: MINIMAL ⊂ COMMUNITY ⊂ ENTERPRISE ⊂ HYPERSCALER.
See RELEASE_STRATEGY.md for the full feature comparison and edition matrix.
