Master Hibernate and JPA with Spring Boot in 100 Steps - Step 73 - Hibernate and JPA Caching - Basics of Second-Level Ca

The video tutorial explains the concept of first and second level caching in Hibernate, focusing on the configuration and implementation of a second level cache using Ehcache. It covers the necessary steps to add dependencies, configure caching properties, and implement selective caching strategies to optimize data management in applications.

What is the primary difference between the first and second level cache in Hibernate?

• Second level cache requires configuration, first level does not.

• Both caches require configuration.

• Neither cache requires configuration.

• First level cache requires configuration, second level does not.

Which dependency is necessary to implement a second level cache using Ehcache?

• org.hibernate:hibernate-core

• org.hibernate:hibernate-ehcache

• org.hibernate:hibernate-entitymanager

• org.hibernate:hibernate-validator

What is the first step in configuring a second level cache in Hibernate?

• Specify the caching framework.

• Add the Ehcache dependency.

• Define cacheable entities.

• Enable the second level cache.

Which property is used to enable the second level cache in Hibernate?

• hibernate.cache.use_query_cache

• hibernate.cache.use_second_level_cache

• hibernate.cache.use_structured_entries

• hibernate.cache.use_minimal_puts

What does the 'enable selective' option do in shared cache mode?

• Caches all entities by default.

• Disables caching for all entities.

• Enables caching only for entities marked as cacheable.

• Enables caching for all entities except those marked as non-cacheable.

Which annotation is used to mark an entity as cacheable in Hibernate?

• @EnableCache

• @Cache

• @EntityCache

• @Cacheable

Why is it not advisable to enable caching for all entities in a typical application?

• It requires additional configuration for each entity.

• Most data in applications changes frequently, making caching inefficient.

• Most data in applications is static and does not require caching.

• It increases the complexity of the application.
