Why should I use lazy loading?The so-called lazy loading, is delayed loading or delayed loading.When the amount of data we access is too large, obviously the cache is inappropriate, because the content capacity is limited, in order to reduce the concurrency, reduce the consumption of system resources, we let the data when needed to load, then we use lazy loading.Hibernate provides lazy loading of propertiesA.

difference is concurrency. With MyISAM, a DML statement would obtain an exclusive lock on the table, and while that lock are held, no other session can Perform a SELECT or a DML operation on the table.Another big difference is concurrency. Using the MYISAM,DML statement will obtain an exclusive lock on the table, and no other session can perform a select or DML operation on the table when the lock is persisted.）Those specific engines you asked about (InnoDB and MyISAM) has different design goal
