Configuration

Starlake Skills helps you configure every aspect of your data pipeline — from database connections to environment-specific overrides.

Configuration Skills

Skill	Purpose
config	Full configuration reference (env vars, application structure, types, best practices)
connection	Create and modify database connections in application.sl.yml
settings	Application-level settings (parallelism, logging, engine options)

Core Configuration Files

File	Purpose
metadata/application.sl.yml	Global config, connections, default settings
metadata/env.sl.yml	Environment variables and path definitions
metadata/env.{ENV}.sl.yml	Environment-specific overrides (DEV, PROD)
metadata/types/default.sl.yml	Data type definitions and mappings
