Housekeeping

  • I am a maintainer of dbt-core

Short description

Currently, if you have duplicate keys in your profiles.yml, dbt just uses the last one.

my_profile:
  ...
  
my_profile:
  ...

This pattern - duplicated yaml keys that silently overwrite - is not one we want to continue to support.

We should throw a deprecation warning with associated telemetry for this in dbt-core v1.10, and then eventually remove support entirely.

Acceptance criteria

If you have duplicate top-level keys in profiles.yml - throw a deprecation warning.
