    InnoDB 1.1 for MySQL 5.5 User's Guide InnoDB 1.1 for MySQL 5.5 User's Guide Abstract This is the User's Guide for the InnoDB storage engine 1.1 for MySQL 5.5. Beginning with MySQL version 5.1, it is possible to swap out one version of the InnoDB storage engine and use another (the “plugin”). This manual documents the latest InnoDB plugin, version 1.1, which works with MySQL 5.5 and features cutting-edge improvements in performance and scalability. This User's Guide documents the procedures and features that are specific to the InnoDB storage engine 1.1 for MySQL 5.5. It supplements the general InnoDB information in the MySQL Reference Manual. Because InnoDB 1.1 is integrated with MySQL 5.5, it is generally available (GA) and production-ready. WARNING: Because the InnoDB storage engine 1.0 and above introduces a new file format, restrictions apply to the use of a database created with the InnoDB storage engine 1.0 and above, with earlier versions of InnoDB, when using mysqldump or MySQL replication and if you use the older InnoDB Hot Backup product rather than the newer MySQL Enterprise Backup product.

    InnoDB Plugin 1.0 for MySQL 5.1 User's Guide InnoDB Plugin 1.0 for MySQL 5.1 User's Guide Abstract This is the User's Guide for InnoDB Plugin 1.0.8 for MySQL 5.1. Starting with version 5.1, MySQL AB has promoted the idea of a “pluggable” storage engine architecture , which permits multiple storage engines to be added to MySQL. Beginning with MySQL version 5.1, it is possible for users to swap out one version of InnoDB and use another. The pluggable storage engine architecture also permits Innobase Oy to release new versions of InnoDB containing bug fixes and new features independently of the release cycle for MySQL. This User's Guide documents the installation and removal procedures and the additional features of the InnoDB Plugin 1.0.8 for MySQL 5.1. WARNING: Because the InnoDB Plugin introduces a new file format, restrictions apply to the use of a database created with the InnoDB Plugin with earlier versions of InnoDB, when using mysqldump or MySQL replication and if you use the InnoDB Hot Backup utility.

  • Mysql Storage Engines Data in Mysql Is Stored in Files (Or Memory) Using a Variety of Different Techniques
    MySQL Storage Engines Data in MySQL is stored in files (or memory) using a variety of different techniques. Each of these techniques employs different storage mechanisms, indexing facilities, locking levels and ultimately provides a range of different functions and capabilities. By choosing a different technique you can gain additional speed or functionality benefits that will improve the overall functionality of your application. For example, if you work with a large amount of temporary data, you may want to make use of the MEMORY storage engine, which stores all of the table data in memory. Alternatively, you may want a database that supports transactions (to ensure data resilience). Each of these different techniques and suites of functionality within the MySQL system is referred to as a storage engine (also known as a table type). By default, MySQL comes with a number of different storage engines pre-configured and enabled in the MySQL server. You can select the storage engine to use on a server, database and even table basis, providing you with the maximum amount of flexibility when it comes to choosing how your information is stored, how it is indexed and what combination of performance and functionality you want to use with your data. This flexibility to choose how your data is stored and indexed is a major reason why MySQL is so popular; other database systems, including most of the commercial options, support only a single type of database storage. Unfortunately the 'one size fits all approach' in these other solutions means that either you sacrifice performance for functionality, or have to spend hours or even days finely tuning your database.

  • Berkeley DB and Sqlite
    Oracle Berkeley DB SQL API vs. SQLite API – Integration, Benefits and Differences ORACLE WHITE P A P E R | NOVEMBER 2 0 1 6 Introduction Oracle's Berkeley DB 12.1.6.2 release offers a perfect combination of technologies by including an SQL API that is fully compatible with SQLite. It is a great example of open source and commercial collaboration offering something for both camps. As a Berkeley DB developer, you now have a proven embedded SQL engine and C API to make application development even easier. And as an SQLite user, you have the option of a powerful, industry-supported storage engine that is built from the ground up for high-concurrency, and which includes powerful features like built-in replication and hot backup. The combination of the two technologies provides you with tremendous flexibility in that a single SQL API can now be used across a broad spectrum of applications ranging from the embedded space all the way up to large-scale transaction processing. For the most part, if you have written code using SQLite, it should be easy to put Berkeley DB's SQL API to use. However, as with all things, there are a few technical caveats you should be mindful of. This paper explores the benefits and potential issues for those familiar with SQLite wanting to test drive the new Oracle Berkeley DB. The Oracle Berkeley Database Architecture The first thing to consider is — what the Oracle Berkeley DB (BDB) SQL interface is and what it is not. If you have worked with MySQL, you may be tempted to think of this new feature as an alternate backend storage module for SQLite, like InnoDB is to MySQL.
