Control Plane for Tables in Open Data Lakehouses

OpenHouse is an open source control plane designed for efficient management of tables within open data lakehouse deployments. The control plane comprises a **declarative catalog** and a suite of **data services**. Users can seamlessly define Tables, their schemas, and associated metadata declaratively within the catalog. OpenHouse reconciles the observed state of Tables with the desired state by orchestrating various data services.

## Getting Started ### Prerequisites For building and running locally in [Docker Compose](SETUP.md), you would need the following: - [Java](https://www.oracle.com/java/technologies/downloads/) - OpenHouse is currently built with Java 17. - Set the `JAVA_HOME` environment variable to the location of your JDK17. - [Docker](https://www.docker.com/) - [Docker Compose](https://docs.docker.com/compose/) - [Python3](https://www.python.org/downloads/) For deploying OpenHouse to [Kubernetes](DEPLOY.md), you would need the following: - [Helm](https://helm.sh/docs/intro/install/) - [Kubernetes](https://kubernetes.io/docs/setup/) ### Building OpenHouse To build OpenHouse, you can use the following command: ```bash ./gradlew build ``` ### Running OpenHouse with Docker Compose To run OpenHouse, we recommend the [SETUP](SETUP.md) guide. You would bring up all the OpenHouse services, MySQL, Prometheus, Apache Spark and HDFS. ### Deploying OpenHouse to Kubernetes To deploy OpenHouse to Kubernetes, you can use the [DEPLOY](DEPLOY.md) guide. You would build the container images for all the OpenHouse services, and deploy them to a Kubernetes cluster using Helm. ### Compability Matrix OpenHouse is built with the following versions of the open-source projects: | Project | Version | | --- | --- | | [Apache Iceberg](https://iceberg.apache.org/releases/#120-release) | 1.2.0 | | [Apache Spark](https://spark.apache.org/releases/) | 3.1.2 | | [Apache Livy](https://livy.apache.org/) | 0.7.0-incubating | | [Apache Hadoop Client](https://hadoop.apache.org/releases.html) | 2.10.0 | | [Springboot Framework](https://spring.io/projects/spring-boot) | 2.6.6 | | [OpenAPI](https://swagger.io/specification/) | 3.0.3 | ## Contributing We welcome contributions to OpenHouse.
