What JSON file is produced by the dbt source freshness command?

The dbt source freshness command generates a JSON file that contains the freshness data about the source tables in your data warehouse. This information is stored in the sources.json file located in the target directory. The sources.json file includes details such as the last run time for data freshness checks, the current timestamp, and any other pertinent information related to the source tables and their configurations.

This JSON file is critical for understanding the health and timeliness of the data being pulled from your sources, allowing analytics teams to ensure they are working with the most up-to-date data. The other files mentioned, like catalog.json and manifest.json, serve different purposes, such as storing metadata about your models and the overall dbt project structure, while index.html is typically used for documentation purposes and doesn't include freshness data.
