This project is guidance around data access using relational databases, as well as NoSQL databases. It describes the various types of data persistence technologies, as well as when, how, and why they should be used. The guidance will show how various persistence types can be used together to create a highly-scalable system, as well as illustrating the challenges that arise when moving to a polyglot persistent system.

Percona Data Recovery Tool for InnoDB is a free toolkit for recovering lost or corrupted data from InnoDB tables. It provides a way to extract InnoDB's data from files or raw devices in a tab-separated format when standard InnoDB recovery cannot be used for some reason, such as a dropped table, or severe corruption that prevents InnoDB from recognizing the data. It can be used to retrieve deleted tables, recover previous versions of updated rows, or fix InnoDB file corruption after a hardware failure such as a memory fault or bad cabling.

Percona has used these tools to perform MySQL data recovery for many customers, including extremely large datasets. Although the tools are powerful, performing InnoDB data recovery correctly requires expert knowledge of InnoDB's storage format and source code, experience, and intuition.

The goal for Maria-DB is to be a drop-in replacement for MySQL – with more features and better performance.

MariaDB is based on the corresponding version of MySQL, if one exists. For example, MariaDB 5.1.53 is based on MySQL 5.1.53, with some added bug fixes, additional storage engines, new features, and performance improvements. Versions of MariaDB that do not have an equivalently numbered version of MySQL (e.g., MariaDB 5.2.4) contain major new features the developers felt warranted a new version number.

Percona XtraDB is an enhanced version of the InnoDB storage engine for MySQL® and MariaDB®. It has much faster performance than InnoDB and better scalability on modern hardware. XtraDB has more features than InnoDB; these are useful in high-load environments. It is backwards-compatible with InnoDB, so you can use it as a drop-in replacement.

Percona XtraDB includes all of InnoDB's reliable ACID-compliant design and advanced MVCC architecture. It adds features, tunability, metrics, and scalability. In particular, it is designed to scale better than InnoDB on many cores, to use memory more efficiently than InnoDB, and to be more convenient and usable than InnoDB. The new features are specially designed to overcome some of InnoDB's limitations. We choose enhancements based on customer requests, and on our best judgment of real-world needs as a high-performance consulting company.

The Percona XtraDB engine does not have separate binary releases. It is available as part of Percona Server and MariaDB.

All of Percona‘s software is open-source and free, all the details of the release can be found in the release notes and 2.2.5 milestone at Launchpad.
