InnoDB is a storage engine for MySQL relational databases, which is used by famous open-source script-powered web applications such as Magento and Joomla™ 3.x. It’s perfect for scalable apps, as it works exceptionally well when managing huge volumes of data. Instead of locking the whole database table to import new information into a database as many other engines do, InnoDB locks only one row, so it can perform a lot more operations for the same period of time. Furthermore, InnoDB offers a much faster database failure recovery and supports transactions and foreign keys – rules that define how data inserts and updates should be treated. In case a given task hasn’t been fully completed for whatever reason, the action will be rolled back. Thus, the database content will be preserved intact and will not be partially merged with newly inserted content.
