# hydra-db/hydradb

> HydraDB is a distributed graph database written in Rust that stores the graph durably on S3-compatible object storage, with separate data nodes and indexers. It supports OpenCypher queries, GraphBLAS traversal, Neo4j Bolt 5.x drivers, and an HTTPS query API.

## Useful for

- Run a single-node HydraDB via Docker for local graph development
- Connect an existing Neo4j application to HydraDB over Bolt 5.x
- Scale indexers separately from data nodes to rebuild traversal indexes

## Why it’s here

- 84 stars so far today, about 297 expected by the end of the day. The usual pace is 70 per day, so that's 4.2× as much.
- Over the last two days the pace is 39× that of the previous week and a half.
- GitHub Trending Rust today: #8, +794 stars.
- About 152 forks a day — people are taking the code.

## Star trust

Star growth looks organic.

Star-trust labels are heuristics based on the repository’s behavior, not a check of every stargazer.

## Numbers

- Forks: 1,168
- Issues and pull requests: 215
- Watchers: 7
- Average over the last week: 164 per day
- Usual pace: 70 per day
- Stars in the last hour (measured): 20

Magnitude (0–10) measures how fast and how unusually interest in a repository is growing right now. It is not a quality score.
Days are UTC. “So far today” is a fact; “expected by the end of the day” is a forecast.
Summaries and use cases are written by an LLM (DeepSeek V4.1 Flash) from the README and may be inaccurate: verify specific claims (benchmarks, speed, hardware) in the repository itself.
