Materialized Views and Caching
Learn how to use materialized views and caching to boost database performance through precomputed query results.
We'll cover the following...
Every day, the management team at our OnlineStore reviews a dashboard that displays the total sales for each product category, the top 10 best selling products for the month, and the number of orders received per day.
To retrieve this information, the database must run several complex queries that join multiple large tables (Orders, Order_Details, Products, Categories) and perform calculations. If dozens of managers are loading this dashboard throughout the day, these same heavy queries will run repeatedly, slowing down the entire system for everyone, including customers trying to make a purchase.
How can we provide this data instantly without overwhelming our database? This is where materialized views and caching come to the rescue. In this lesson, we will explore these powerful optimization techniques to supercharge our query performance.
By the end of this lesson, we will be able to:
Understand the difference between a standard view and a materialized view.
Create and manage materialized views to pre-compute and store query results.
Recognize the benefits and trade-offs of using materialized views, especially regarding data freshness.
Grasp the concept of caching and its role in database performance.
Materialized view
We already know that a standard view is essentially a stored SQL query that behaves like a table.
Views simplify complex queries, but they ...
