Complete configuration:

models:
  materialized: table       // table or view or materialized_view
  engine: 'OLAP'
  keys: ['id', 'name', 'some_date']
  table_type: 'PRIMARY'     // PRIMARY or DUPLICATE or UNIQUE
  distributed_by: ['id']
  buckets: 3                // default 10
  partition_by: ['some_date']
  partition_by_init: ["PARTITION p1 VALUES [('1971-01-01 00:00:00'), ('1991-01-01 00:00:00')),PARTITION p1972 VALUES [('1991-01-01 00:00:00'), ('1999-01-01 00:00:00'))"]
  properties: [{"replication_num":"1", "in_memory": "true"}]
  refresh_method: 'async' // only for materialized view default manual

dbt run config:

Example configuration:

{{ config(materialized='view') }}
{{ config(materialized='table', engine='OLAP', buckets=32, distributed_by=['id']) }}
{{ config(materialized='incremental', table_type='PRIMARY', engine='OLAP', buckets=32, distributed_by=['id']) }}
{{ config(materialized='materialized_view') }}
{{ config(materialized='materialized_view', properties={"storage_medium":"SSD"}) }}
{{ config(materialized='materialized_view', refresh_method="ASYNC START('2022-09-01 10:00:00') EVERY (interval 1 day)") }}

For materialized view only support partition_by、buckets、distributed_by、properties、refresh_method configuration.
