Browse, install, and run pre-built demo datasets and SQL tutorials.
## Overview The Demo Gallery page presents a catalog of pre-built demo datasets and SQL tutorials that ship with DeltaForge. New users and evaluators use this page to quickly provision working examples that demonstrate platform capabilities such as Delta table querying, graph analytics, lineage extraction, and pipeline scheduling. Each demo includes seed data, setup SQL, query scripts, and cleanup SQL, all packaged for one-click installation. The gallery retrieves its catalog from the control plane API and tracks installation state per demo so that users can see which demos are already provisioned, which are available, and which require a data download before installation. ## Key Features - Browse the full demo catalog with title, description, category tags, and estimated installation size for each entry. - Provision a demo with a single click. The provisioning process executes the setup SQL, creates the required zones, schemas, tables, and graph definitions, and loads the seed data. - Download demo data packages when the seed data is not bundled with the application. The download progress is displayed inline. - Track installation status for every demo. Statuses include Available, Downloading, Installing, Installed, and Failed. Failed installations display an error summary with a retry option. - Remove an installed demo by running its cleanup SQL, which drops all objects and data created during provisioning. - Open the query scripts for an installed demo directly in the SQL editor to begin exploring immediately. ## Workflow 1. Navigate to the Home section and select Demo Gallery. 2. Browse or filter the catalog to find a demo that matches the feature area of interest. 3. Click Install on the desired demo. If the demo requires a data download, the download begins automatically before installation. 4. Wait for the provisioning process to complete. The status indicator transitions from Installing to Installed on success. 5. Click Open Queries to launch the demo's SQL scripts in the editor. Execute the queries to explore the demo dataset. 6. When finished, return to the gallery and click Remove to clean up the demo objects and reclaim storage.
