dbt - YAML 文件中的 +/- 是什么？

Question

在 DBT YAML 文件（例如 dbt_project.yml）中，元素是什么+或符号是什么？-

models:
  # Be sure to namespace your model configs to your project name
  dbt_labs:

    # This configures models found in models/events/
    events:
      +enabled: true            # <--- What is the meaning of +?
      +materialized: view       # <--- What is the meaning of +?

      # This configures models found in models/events/base
      # These models will be ephemeral, as the config above is overridden
      base:
        +materialized: ephemeral       # <--- What is the meaning of +?

Answer 1

“-”是标准 YAML 语法，表示“列表”项：docs.ansible.com > YAML Basisc

“+”是 DBT 特有的，表示一个子类别，如“+indexes”、“+tags”。这只是 DBT 约定。docs.getdbt.com > Materialize 配置。
