Jinja Function 当需求变得更复杂时,如果仅仅通过SQL实现转换将会很困难,所以可以通过Jinja Function来实现在SQL中无法做到的事。 比如在有多个Model的dbt工程中,通常会有一些可以复用的逻辑,类似于编程语言中的函数。有了Jinja Function,就可以把要复用的逻辑提取成单独的Model,然后在其他Model中通过表达式{{ ref() }...

The obvious difference is the ELT process performs the Load function before the Transform function – a reversal of the second and third steps of the ETL process. ELT copies or exports the data from the source locations, but instead of moving it to a staging area for transformation, it loads...
