Lakehouse-native graph engine with git-style workflows
https://omnigraph.dev
6dc4167291
Three independent automated reviews (Cubic P1, Cursor High, Codex P1) flagged a real correctness bug in stage_merge_insert: Operation::Update returns three fields — removed_fragment_ids, updated_fragments, new_fragments — and we were collecting only the latter two into StagedWrite.new_fragments while discarding removed_fragment_ids. That breaks read-your-writes for any merge_insert that rewrites an existing fragment: scan_with_staged combines the dataset's full committed manifest with the staged new_fragments, so the *original* committed fragment (which the rewrite supersedes) and its rewritten version both end up in the Scanner's fragment list. Result: duplicate rows. Fix: - StagedWrite gains `removed_fragment_ids: Vec<u64>` populated from Operation::Update; empty for Operation::Append (which never supersedes existing fragments). - scan_with_staged / count_rows_with_staged take `&[StagedWrite]` instead of `&[Fragment]` so they have access to both fields. - A new `combine_committed_with_staged` helper composes the visible fragment list as `committed - removed + new`, deduping by fragment ID. Also addresses cubic's P3 doc-fab note: the StagedWrite doc comment claimed the type was "used by MutationStaging and the loader" but those callers don't exist in this PR (they're MR-794 step 2+). Reword to "defined here for later integration" so the doc doesn't lie about the current state. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> |

Omnigraph
Lakehouse-native graph engine with git-style workflows.
Branch, commit, and merge typed graph data like source code. Multi-modal, self-hosted, open source.
Use Cases
- On-prem & hybrid context graphs
- Backbone for multi-agent research
- Incident response graphs
- Compliance & audit graphs
- Enterprise knowledge systems
Capabilities
- Typed schema, typed queries, and typed mutations
- Schema-as-code, query validation and linting
- Git-style graph workflows: branches, commits, merges, and transactional runs
- Local, on-prem & cloud S3-native storage with snapshot-pinned reads
- Graph traversal + text, fuzzy, BM25, vector, and RRF search in one runtime
- Policy-as-code for server-side access control
- Single CLI for multiple deployments
Quick Install
curl -fsSL https://raw.githubusercontent.com/ModernRelay/omnigraph/main/scripts/install.sh | bash
This installs omnigraph and omnigraph-server into ~/.local/bin from
published release binaries.
Or install with Homebrew:
brew tap ModernRelay/tap
brew install ModernRelay/tap/omnigraph
For starter graphs and agent skills to bootstrap and operate Omnigraph, see ModernRelay/omnigraph-starters.
One-Command Local RustFS Bootstrap
curl -fsSL https://raw.githubusercontent.com/ModernRelay/omnigraph/main/scripts/local-rustfs-bootstrap.sh | bash
That bootstrap:
- starts RustFS on
127.0.0.1:9000 - creates a bucket and S3-backed repo
- loads the checked-in context fixture
- launches
omnigraph-serveron127.0.0.1:8080
Docker must be installed and running first.
The RustFS bootstrap prefers the rolling edge binaries and only falls back to
source builds when release assets are unavailable.
If a previous run left objects under the same repo prefix but did not finish
initializing the repo, rerun with RESET_REPO=1 or set PREFIX to a new
value.
Common Commands
The same URI works for local paths, s3://…, or http://host:port.
omnigraph init --schema ./schema.pg ./repo.omni
omnigraph load --data ./data.jsonl ./repo.omni
omnigraph read --query ./queries.gq --name get_person --params '{"name":"Alice"}' ./repo.omni
omnigraph change --query ./queries.gq --name insert_person --params '{"name":"Mina"}' ./repo.omni
omnigraph branch create --from main feature-x ./repo.omni
omnigraph branch merge feature-x --into main ./repo.omni
See docs/cli.md for schema apply, snapshots, ingest, runs, and policy commands.

Build And Test
cargo build --workspace
cargo check --workspace
cargo test --workspace
Notes:
- Rust stable toolchain, edition 2024
- CI runs
cargo test --workspace --locked - Full CI and some local test flows require
protobuf-compiler - S3 integration tests expect an S3-compatible endpoint such as RustFS
