Kùzu

Kùzu is an in-process property graph database management system (GDBMS) built for query speed and scalability. Kùzu is optimized for handling complex join-heavy analytical workloads on very large graph databases, with the following core feature set:

Flexible Property Graph Data Model and Cypher query language
Embeddable, serverless integration into applications
Columnar disk-based storage
Columnar sparse row-based (CSR) adjacency list/join indices
Vectorized and factorized query processor
Novel and very fast join algorithms
Multi-core query parallelism
Serializable ACID transactions

Kùzu is being actively developed at University of Waterloo as a feature-rich and usable GDBMS. Kùzu is available under a permissible license. So try it out and help us make it better! We welcome your feedback and feature requests.

Installation

Please refer to our website for installation and usage instructions.

Development

For development, Kùzu requires Bazel, Python 3, and a compiler that supports C++20.

Bazel configuration

Create bazel configuration file with touch .bazelrc
Add bazel configuration echo build --cxxopt="-std=c++2a" --cxxopt='-O3' > .bazelrc

Bazel build

To do a full clean build
- bazel clean --expunge
- bazel build //...:all
To test
- bazel test //...:all

We are developing Kùzu in a publicly open github repo and encourage everyone to comment and discuss topics related to Kùzu. However we ask everyone to be very respectful and polite in discussions and avoid any hurtful language in any form. Kùzu is being developed in Canada, a land that is proud in their high standards for politeness and where a person you bumped into on the road will likely apologize to you even if it was your fault: so please be kind and respectful to everyone.
