`config`对象具有物化信息。您可以直接从那里查找。
{%- set materialization = config.get('materialized') -%}
值可以是`table`、`view`、`incremental`或`ephemeral`之一。
英文:
The config object has the materialization. You can look it up directly from there.
{%- set materialization = config.get('materialized') -%}
Value will be one of table, view, incremental, or ephemeral
