在第一篇文章中,我们知道dbt run可用于启动并运行整个 dbt 项目,一个命令可直接运行你项目中的所有 models,但事实上有时候我们只更新了一个 model,且我只希望更新这一个 model,那么这时候你可以通过--select指定你需要运行的 model。 这是运行指定条件 model 的一些说明: dbt run--select"my_dbt_project_name"...
第四条命令用于运行指定 package 下某个目录下的所有模型,它与第三条命令的区别在于一个是我们自己的 dbt 项目,一个是我们引入的三方包,我知道你在想那我不如直接dbt run --select model来运行某个模型,何必指定包名;有些时候引入的包过多可能存在 model 重名的情况,那么指定包名可以解决这个问题: dbt run --...
dbt runminimizes the amount of time in which a model is unavailable by first building each model with a temporary name, then dropping the existing model, then renaming the model to its correct name. The drop and rename happen within a single database transaction for database adapters that ...
Dramatically reduce the time your queries take to run: Leverage metadata to find long-running models that you want to optimize and useincremental modelswhich dbt makes easy to configure and use. WriteDRYer code by leveragingmacros,hooks, andpackage management. ...
激活虚拟环境后,使用上述两个文件的路径运行dbt run命令。 在default数据库中(如profiles.yml文件中指定),dbt 会创建一个名为zzz_game_details的表和一个名为zzz_win_loss_records的视图。 dbt 从相关的.sql文件名获取这些视图和表名称。 Bash dbt run --model models/zzz_game_details.sql models/zzz_win_lo...
** Kirundi (Rundi): newly added language, spoken in Burundi. ** Kituba: newly added language, spoken in Congo. Korean: braille-to-print translation has minor corrections. Korean localization is markedly improved. ** Leb-Lango: newly added language, spoken in Uganda. ** Lisu: newly added ...
Theincrementalmaterialization is an advanced strategy best used on models that are large enough that you don’t want to do a full refresh on every run. Instead of reprocessing an entire dataset every time a model is run, incremental models process a smaller number of rows with new data, and...
dbt is also available as open source software for analytics engineers who want to set up and run dbt locally or on their own infrastructure. dbt Core™ is distributed under the Apache 2.0 license. dbt Core™ is best suited for small, highly technical teams with simpler dbt deployments. db...
It is important to be descriptive in model names. Inside the model (.sql file), paste this dummy test SQL query: SELECT 1 AS Id Powered By and run the model with dbt run: $ dbt run Powered By You should receive a green “Completed successfully” message. After everything is ...
接下来就可以运行命令dbt run来启动dbt的transformation任务.由于项目初始化的时候就已经提供了2个example...
