support multiple unique key (composite primary key)

[imfaridz]

Hi,

I encounter this issue when execute dbt-dry-run to a table that has multiple unique key or composite primary key:

nodes -> model.dbt_re_data_test.table_name -> config -> unique_key
  str type expected (type=type_error.str)

need support to be able to include list type for multiple column unique_key

Hey @imfaridz,

Thanks for raising an issue. Looks like support for this was added in dbt-core 1.1 in this PR

Setting unique_key as a list is only supported for incremental tables so this issue will be fairly easy to fix as only the snapshot_runner
uses unique_key when validating the model config.

I will raise a PR to update our pydantic model schema

Will do a patch release for this sometime this week now the PR is merged

thanks for the support @connor-charles !
