Spring Boot JPA DynamicUpdate
 Is it Suggestable to use Dynamic Update?
 Is Performance wise is good?
There are a few scenarios where we should use this annotation — for example, if an entity represents a table that has a large number of columns and only a few of these columns are required to be updated frequently
When we use @DynamicUpdate on an entity, JPA does not use the cached SQL statement for the update. Instead, it will generate an SQL statement each time we update the entity. This generated SQL includes only the changed columns.
In order to find out the changed columns, JPA needs to track the state of the current entity. So, when we change any field of an entity, it compares the current and the modified states of the entity.
I will explain to you both ways to update an entity: with or without DynamicUpdate

Example:
@Entity
@Table(name=”XXXXX”)
@DynamicUpdate
class Demo{
………….
}

Note: If you don't know how to set a base project. Please follow the spring boot tutorial
