Materialize a view

Learn how to materialize a View to improve its performance.

To improve the performance of a View, you can materialize it. This operation computes the data for the View and stores it in memory, just like a table. You can expect a 3-6 times performance improvement on a Materialized View over a View that is not materialized. However, materialized Views take up space in memory, so weigh the tradeoffs and benefits of materializing a View ahead of time.

Row Level Security does not apply to Materialized Views. All users will see the same data when using the Materialized View as a data source.

To materialize a view:

  1. To find your View, click Data in the top menu, and choose Views.

  2. Click the name of your View.
