dbt select支持的方法简单说明
对于一个大型的dbt 项目，我进行按需选择模型还是很重要的，dbt 基于select 可以支持多样的选择方法
支持的模式
- tag 模式
dbt run --select "tag:nightly"
- source 模式
dbt run --select "source:snowplow+"
- 资源类型模式
dbt build --select "resource_type:exposure"
dbt list --select "resource_type:test"
- 路径模式
# These two selectors are equivalent
dbt run --select "path:models/staging/github"
dbt run --select "models/staging/github"
# These two selectors are equivalent
dbt run --select "path:models/staging/github/stg_issues.sql"
dbt run --select "models/staging/github/stg_issues.sql"
- 文件模式
dbt run --select "file:some_model.sql"
dbt run --select "some_model.sql"
dbt run --select "some_model"
- fqn 模式
dbt run --select "fqn:some_model"
dbt run --select "fqn:your_project.some_model"
dbt run --select "fqn:some_package.some_other_model"
dbt run --select "fqn:some_path.some_model"
dbt run --select "fqn:your_project.some_path.some_model"
- package 模式
# These three selectors are equivalent
dbt run --select "package:snowplow"
dbt run --select "snowplow"
dbt run --select "snowplow.*"
- config 模式
dbt run --select "config.materialized:incremental"
dbt run --select "config.schema:audit"
dbt run --select "config.cluster_by:geo_country"
- 测试类型模式
dbt test --select "test_type:generic"
dbt test --select "test_type:singular"
- 测试方法模式
dbt test --select "test_name:unique"
dbt test --select "test_name:equality"
dbt test --select "test_name:range_min_max"
- 状态模式
dbt test --select "state:new" --state path/to/artifacts
dbt run --select "state:modified" --state path/to/artifacts
dbt ls --select "state:modified" --state path/to/artifacts
- exposure模式
dbt run --select "+exposure:weekly_kpis"
dbt test --select "+exposure:*"
dbt ls --select "+exposure:*" --resource-type snowplow
- metrics 模式
dbt build --select "+metric:weekly_active_users"
dbt ls --select "+metric:*" --resource-type source
- result 模式
dbt run --select "result:error" --state path/to/artifacts
dbt test --select "result:fail" --state path/to/artifacts
dbt build --select "1+result:fail" --state path/to/artifacts
dbt seed --select "result:error" --state path/to/artifacts
- source_status 模式
dbt source freshness
dbt build --select "source_status:fresher+"
- group 模式
dbt run --select "group:finance"
- 访问模式
dbt list --select "access:public"
dbt list --select "access:private"
dbt list --select "access:protected"
- 版本模式
dbt list --select "version:latest"
dbt list --select "version:prerelease"
dbt list --select "version:old"
dbt list --select "version:none"
- 语义模型模式
dbt list --select "semantic_model:*"
dbt list --select "+semantic_model:orders"
- 保存查询模式
dbt list --select "saved_query:*"
dbt list --select "+saved_query:orders_saved_query"
说明
以上是选择的简单说明，实际上dbt 在处理的时候还支持基于graph 的操作实现比较灵活的选择执行，详细的使用还是得多练习
