 | [Incremental Materialized View](/materialized-view/incremental-materialized-view) | Allow users to shift the cost of computation from query time to insert time, resulting in faster `SELECT` queries.                                                                             |
 | [Refreshable Materialized View](/materialized-view/refreshable-materialized-view) | Conceptually similar to incremental materialized views but require the periodic execution of the query over the full dataset - the results of which are stored in a target table for querying. |
