1) Validate the asset contracts

From the parent directory, validate the template before it touches ClickHouse:

bruin validate clickhouse-bruin-101 --fast

Validation checks the asset definitions and their dependencies. It catches problems such as an invalid materialization configuration, a missing dependency, or a malformed declared column before a run starts. The --fast option keeps this first pass focused on static validation. See the Bruin validate command for the checks available in your CLI version.

This command has two useful parts:

• clickhouse-bruin-101 is the project directory, so Bruin reads its pipeline and all of its assets.
• --fast avoids running the pipeline or querying every external connection. It is the first check to run after editing an asset definition.
