# delta vs omnigraph

*GraphCanon updated Aug 3, 2026*

## Verdict

Pick delta if delta is an open-source storage framework providing ACID transactions for data lakehouse architectures designed to work seamlessly with various compute engines including Apache Spark, PrestoDB, Flink, Trino, and Hive; pick omnigraph if omnigraph is a Rust-based Lakehouse-native graph engine that integrates Git-style workflows for managing knowledge graphs leveraging modern data technologies such as Apache Arrow and DataFusion.

[delta](https://delta.io) reports 8.9k GitHub stars, 2.1k forks, and 1.6k open issues, last pushed Aug 2, 2026. [omnigraph](https://omnigraph.dev) has 1.0k stars, 190 forks, and 17 open issues, last pushed Aug 2, 2026. Figures are from public GitHub metadata via [delta's repository](https://github.com/delta-io/delta) and [omnigraph's repository](https://github.com/ModernRelay/omnigraph).

## Decision facts: delta

- **Adopt for:** Delta is an open-source storage framework providing ACID transactions for data lakehouse architectures designed to work seamlessly with various compute engines including Apache Spark, PrestoDB, Flink, Trino, and Hive.

## Decision facts: omnigraph

- **Adopt for:** Omnigraph is a Rust-based Lakehouse-native graph engine that integrates Git-style workflows for managing knowledge graphs leveraging modern data technologies such as Apache Arrow and DataFusion.

## Choose when

### Choose delta if…

- delta is primarily Scala; omnigraph is Rust.
- License: delta is Apache-2.0, omnigraph is MIT.
- Tags unique to delta: acid, analytics, big-data, delta-lake.
- When you need ACID transaction support in a data lakehouse architecture leveraging Scala and multiple compute engines like Spark, Flink, or PrestoDB.

### Choose omnigraph if…

- omnigraph is primarily Rust; delta is Scala.
- License: omnigraph is MIT, delta is Apache-2.0.
- Tags unique to omnigraph: apache-arrow, context-graph, datafusion, graph-database.
- Use Omnigraph if your project involves complex knowledge graph management within a lakehouse architecture, as it offers native integration to facilitate efficient handling of large datasets.

## When NOT to use delta

- When your data operations environment is restricted to a single compute engine or one not supported by Delta, like Apache Drill which isn't in the listed support scope.
- If your project strictly uses open-source licenses incompatible with BSD-style licensing terms, as Delta uses Apache-2.0.
- For situations where there's no need for advanced data management capabilities such as ACID transactions and you can manage with simpler storage solutions.

## When NOT to use omnigraph

- Avoid Omnigraph if you prefer or need a Java-based solution, as it might not align with the runtime requirements of your existing technology stack.
- Omnigraph may not be suitable for simple or small-scale graph projects that do not require advanced versioning and collaboration features akin to Git workflows.
