Three follow-ups to the staged-writes primitives, all caught by the "are we missing tests?" review: (1) Path A row-ID threading (Gap 1, real bug): stage_append now takes prior_stages: &[StagedWrite] and offsets the assigned row IDs by the sum of prior stages' physical_rows. Without this, two stage_appends against the same dataset both started at ds.manifest.next_row_id, producing fragments with overlapping _rowid ranges. This would have fired in Step 2+ on any multi-statement mutation like `insert Knows ...; insert Knows ...` (multiple appends to the same edge table — allowed under D₂′). The slice mirrors scan_with_staged's API shape; the same slice is passed to both stage and scan. Documented contract: only stage_append results in prior_stages (D₂′ guarantees this upstream). (2) commit_staged round-trip tests (Gap 2): Two tests covering stage_append + commit_staged and stage_merge_insert + commit_staged. Validate that Lance's commit-time row-ID assignment works correctly even after our pre-commit row_id_meta assignment in the append path — the two assignments diverge but neither is observed across the boundary. (3) Filter pushdown test (Gap 3): scan_with_staged with a SQL filter applies it across both committed and staged fragments. Validates the MR-794 ticket's claim that Lance's with_fragments preserves filter/vector/FTS pushdown (Lance tests test_scalar_index_respects_fragment_list etc.). Also adds chained_stage_appends_have_distinct_row_ids which directly demonstrates the Gap 1 fix by projecting _rowid and asserting no duplicates across 1 committed + 2 staged rows.

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
