It enables rapid query responses, but to keep the state up to date after a underlying table is modified, materialized views require to be refreshed. | SlidesVideo |

For example, the foreign key constraint in PostgreSQL relies on the triggers internally. | Slides |

In this talk, we will discuss what is necessary to implement IVM and our idea about the first version of IVM implementation on PostgreSQL. | Slides |
