Open Lakehouse Compute Fabric
Open Lakehouse Compute Fabric is an open-source lakehouse platform provides Spark compute, SQL editing, notebooks, pipelines, and governance tools.
Open Lakehouse Compute Fabric is an open-source lakehouse platform that runs on a single laptop, on-premises machines, cloud virtual machines, or Kubernetes. It provides a web console, REST API, CLI, and Python SDK with workspaces, lakehouses, a SQL editor, dashboards, Jupyter-compatible notebooks, pipelines, and administration tools. It features a distributed Spark compute fabric where worker agents connect to a control plane to form a Spark Standalone cluster. Users can extend Microsoft Fabric by running notebooks on their own hardware while reading and writing OneLake directly. The platform includes OLCF Intelligence for discovery, lineage, a business glossary, and governance across connected assets. It also provides an MCP endpoint so AI agents can browse the catalog and run read-only SQL queries.
