Fix A: op-kind-aware ensure_expected_version. Insert/Merge skip the strict pre-stage check; Update/Delete/SchemaRewrite keep it. New MutationOpKind enum threaded through open_for_mutation_on_branch / open_owned_dataset_for_branch_write / reopen_for_mutation and all callers (execute_insert/update/delete_node/delete_edge, branch_merge::publish_rewritten_merge_table, schema_apply, ensure_indices_for_branch, loader Append/Merge/Overwrite). Closes the 77% rejection rate on same-key concurrent inserts. Fix B: coordinator Mutex -> RwLock. Reads parallelize via .read(); writes serialize via .write(). Atomic-commit invariant preserved by the single .write() covering commit_manifest_updates + record_graph_commit. Bench-as-test change_concurrent_inserts_same_key_serialize_without_409 (server.rs:2180) spawns 12 concurrent /change inserts on a single (table, branch); asserts every request returns 200. Was failing pre-Phase-2; passes post-Phase-2. change_conflict_returns_manifest_conflict_409 (cross-process drift sentinel) and branch_merge_conflict_response_includes_structured_conflicts both still pass. Bench (after-pr2-phase2): - single-actor 1x1: 14.9 ops/s, p50 68ms (baseline 12.3, +22%) - disjoint 8x8: 7.04 ops/s, p50 1023ms (baseline 6.24, +13%) - same-key 8x1: 2.62 ops/s, 0 errors (after-pr2: 77% errors) Disjoint stayed at +13% — Fix B's RwLock helped read paths but the publisher's .write() critical section still serializes graph-wide. Splitting GraphCoordinator into per-concern primitives (manifest in ArcSwap, commit_graph in RwLock, atomic-commit serializer) is the deferred next step. 102 lib + 30 branching + 24 runs + 16 staged_writes + 63 end_to_end + 40 server tests pass.

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-cookbooks.
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
