+|`materializedview`| To be deprecated. |It is available only for backward compatibility purposes (for v1.5.1 of the dbt-risingwave adapter plugin). If you are using v1.6.0 and later versions of the dbt-risingwave adapter plugin, use `materialized_view` instead.|
 |`materialized_view`| Yes| Creates a [materialized view](https://docs.risingwave.com/docs/dev/sql-create-mv/). This materialization corresponds the `incremental` one in dbt. To use this materialization, add `{{ config(materialized='materialized_view') }}` to your model SQL files.|
 | `incremental`|No|Please use `materialized_view` instead. Since RisingWave is designed to use materialized view to manage data transformation in an incremental way, you can just use the `materialized_view` materialization.|
 |`source`| Yes| Creates a [source](https://docs.risingwave.com/docs/dev/sql-create-source/). To use this materialization, add {{ config(materialized='source') }} to your model SQL files. You need to provide your create source statement as a whole in this model. See [Example model files](https://docs.risingwave.com/docs/dev/use-dbt/#example-model-files) for details.|
