Innodb 1.1 for Mysql 5.5 User's Guide Innodb 1.1 for Mysql 5.5 User's Guide
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. See Section 1.4, “Compatibility Considerations for Downgrade and Backup”. For legal information, see the Legal Notices.

A Study of the Innodb Storage Engine in the Mysql 5.6

The logical structure through Online Transaction Processing (OLTP) work. of MySQL is largely divided into three layers and the storage Ubuntu 14.04 LTS (Long Term Support) was used as an engine belongs to the last layer. The purpose of this paper is to operating system and HammerDB was installed to evaluate evaluate the performance of InnoDB engine, the engine that performance with TPC-C. supports transaction of several storage engines used in MySQL 5.6. TPC-C (Transaction Processing performance Council – C), II. MYSQL LOGICAL STRUCTURE : INNODB an international standard model of benchmarking, is used for performance evaluation and performance evaluation was MySQL is an open source relational database carried out by installing HammerDB for this purpose. It was management system currently distributed by Oracle. The found that, if the number of user requests increases and the logical structure of MySQL is largely divided into three number of transaction processing requests increases, then the layers. There is a Handing layer in the highest layer and number of transactions processed in InnoDB also increases. processes DB connection, authentication and security. Parsing of query, analysis, review, optimization and caching Keywords- InnoDB, Storage Engine, TPC-C, MySQL 5.6 are performed in the middle layer of the logical structure in MySQL. -
