## The problem I’m having

> **[Configure incremental models | dbt Developer Hub](https://docs.getdbt.com/docs/build/incremental-models#supported-incremental-strategies-by-adapter)**
>
> Learn how to configure and optimize incremental models when developing in dbt.

Its mentioned here that dbt-redshift will do append in incremental model by default when merge strategy is not provided. But In our project its doing delete+insert. Are the docs correct? Or am I missing something. I have pasted the sample config below

## Some example code or error messages

```auto
{{
  config(
    materialized = 'incremental',
    enabled = true,
    sort = 'date_time',
    dist = 'x',
    alias = 'raw_table' ,
    on_schema_change = 'sync_all_columns',
    unique_key = '(x||y)',
    
    ) 
}} 

```
