InnoDB is a storage engine for MySQL relational databases, which is used by well known PHP script-based software applications such as Joomla v3 and Magento. It’s excellent for scalable applications, because it works exceptionally well when handling enormous data volumes. Rather than locking the entire table to enter new information into a database as many other engines do, InnoDB locks only one row, so it can process much more operations for the same length of time. Plus, InnoDB offers a faster crash recovery and supports database transactions and foreign keys – rules that determine how data imports and modifications should be handled. In case a certain task hasn’t been fully completed for any reason, the action will be rolled back. In this way, the content in the database will remain safe and sound and will not be partially merged with newly entered content.
