Master Hibernate and JPA with Spring Boot in 100 Steps - Step 74 - Hibernate and JPA Caching-Second-Level Cache Part 2

The video tutorial explains how to configure Hibernate to use Ehcache for caching. It covers enabling caching for specific entities, setting logging levels, and observing JDBC statements. The tutorial demonstrates implementing second level cache using annotations and explains cache hits and misses. Key concepts include first and second level caching, and the importance of deciding what data to cache.

What is the primary purpose of configuring Ehcache with Hibernate?

• To enable caching for specific entities

• To increase application logging levels

• To improve database security

• To enhance user interface design

Why is it important to enable logging for Ehcache?

• To see detailed information about caching operations

• To reduce application size

• To disable caching

• To improve network speed

What happens when you refresh the application without caching enabled?

• The same queries are fired multiple times

• The data is retrieved from the cache

• The application speed increases

• The application crashes

How do you enable caching for an entity in Hibernate?

• By using the @Cacheable annotation

• By modifying the database schema

• By changing the URL

• By disabling logging

What is a cache hit in the context of Ehcache?

• When data is not found in the cache

• When data is successfully retrieved from the cache

• When a new cache is created

• When the cache is cleared

What does Ehcache do when there is a cache miss?

• It deletes the cache

• It updates the cache with the new data

• It ignores the request

• It logs an error

Why is it crucial to decide what data to cache?

• To ensure data security

• To optimize cache performance

• To reduce application size

• To increase logging levels
