View Materialization

A dbt model can be created as a Doris view and configured using the following syntax:

• Project file
• Config block

dbt_project.yml

models:
  <resource-path>:
    +materialized: view

Table Materialization

A dbt model can be created as a Doris table and configured using the following syntax:

• Project file
• Config block

dbt_project.yml

models:
  <resource-path>:
    +materialized: table
    +duplicate_key: [ <column-name>, ... ],
    +partition_by: [ <column-name>, ... ],
    +partition_type: <engine-type>,
    +partition_by_init: [<pertition-init>, ... ]
    +distributed_by: [ <column-name>, ... ],
    +buckets: int,
    +properties: {<key>:<value>,...}
