The cache is a type of memory that stores data temporarily in it. This data helps websites, browsers, or apps load or start faster. Whether it is a computer, laptop, or mobile, you will find a variety of cache in it. Because of cache, the data retrieval gets faster, and the speed of apps, websites, or browsers increases. The cache is stored in fast-access hardware, e.g., RAM.
Hibernate has two types of cache: the first is the first level, and another one is the second level. The first level cache is the session-level associated with a session object. The first level cache is used to decrease the interaction of the database by storing the state of the object. It does not constantly update the object after every modification, and it only updates the object at the end of the transaction. This level cache is enabled by default.
