Laravel has another great mechanism for helping its performance in the enterprise: read and write. This is related to database performance, but the functionality is so easy to set up that any application can take advantage of its usefulness.
Regarding MySQL, the original MyISAM database engine required a lock on the entire table during inserts, updates, and deletes. This caused massive bottlenecks during large operations that modified the data and select queries waited to access these tables. With the introduction of InnoDB,
DELETE SQL statements required a lock only at the row-level. This tremendously impacted performance, since selects could read from various parts of a table where other operations were taking place.
MariaDB, a MySQL fork, claims faster performance than the traditional MySQL. Replacing the database engine with TokuDB will give even higher performance, especially in a big data setting.
Another mechanism to speed up performance of the database is the use of a master/slave configuration. In the following diagram, all of the operations are performed on a single table. The inserts and updates will lock down single rows and the select statements will be performed as allocated.
