Configuration

The config file, the runtime lifecycle, and environment variables.

You configure a LakeQL project through lakeql.config.ts and the environment. This section covers the config file structure, the runtime lifecycle that composes it into live data sources, and the environment variables that feed it.

The configuration API lives in @lakeql/config. This section is the project-author view of it.

Config File

The structure of lakeql.config.ts.

Runtime Lifecycle

How config is loaded and composed into a runtime.

Environment Variables
