Materialized View in SQL | Faster SQL Queries using Materialized Views

Improve the performance of your SQL Query using Materialized View. In this video, we learn everything you need to know about Materialized View in PostgreSQL. We learn about what is Materialized View, How does it improve query performance and how does it work?

In order to showcase the performance improvement due to Materialized View, we first create a table and load millions of records into this table and then write an SQL query on it to see the slow query execution time. We then create a Materialized View over this SQL query and execute the Materialized View to see the boost in performance. I shall explain the reason for this performance improvement during the video.
