A Materialized View in Snowflake is a database object that contains the results of a query. It is physically stored and automatically updated as data changes, providing faster access to data.

materialized_view = MaterializedView(
    name="some_materialized_view",
    owner="SYSADMIN",
    secure=True,
    as_="SELECT * FROM some_table",
)
```

### YAML

```yaml
materialized_views:
  - name: some_materialized_view

    secure: true
    as_: SELECT * FROM some_table
