Innodb Plugin 1.0 for Mysql 5.1 User's Guide Innodb Plugin 1.0 for Mysql 5.1 User's Guide 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. See Section 1.5, “Operational Restrictions”. For legal information, see the Legal Notices.

  • TMS Xdata Documentation
    Overview TMS XData is a Delphi framework that allows you to create HTTP/HTTPS servers that expose data through REST/JSON. It is highly integrated into TMS Aurelius in a way that creating XData services based on applications with existing Aurelius mappings are just a matter of a few lines of code. XData defines URL conventions for adressing resources, and it specifies the JSON format of message payloads. It is heavily based on the OData standard. Such conventions, with the benefit of existing Aurelius mapping, allow building a full REST/JSON server with minimum writing of code. TMS XData uses TMS Sparkle as its core communication library. TMS XData product page: https://www.tmssoftware.com/site/xdata.asp TMS Software site: https://www.tmssoftware.com TMS XData is a full-featured Delphi framework that allows you to create REST/JSON servers, using server-side actions named service operations, and optionally exposing TMS Aurelius entities through REST endpoints. Consider that you have an Aurelius class mapped as follows: [Entity, Automapping] TCustomer = class strict private FId: integer; FName: string; FTitle: string; FBirthday: TDateTime; FCountry: TCountry; public property Id: Integer read FId write FId; property Name: string read FName write FName; property Title: string read FTitle write FTitle; property Birthday: TDateTime read FDateTime write FDateTime; property Country: TCountry read FCountry write FCountry; end; With a few lines of code you can create an XData server to expose these objects. You can retrieve an existing TCustomer

This storage performance issues regarding the highly exhausting consumers unit’s variety holds the first problem discussed in this paper: nowadays. The distributed database designers rely on data data exchange format between the heterogeneous nodes in replication to make data as near as possible from the the same Distributed Database Management System requesting systems. The data replication involves a sensitive (DDBMS). The process of transforming raw data from operation to keep data integrity among the distributed architecture: data synchronization. While this operation is source system to an exchange format is called serialization. necessary to almost every distributed system, it needs an in The reverse operation, executed by the receiver side, is depth study before deciding which entity to duplicate and called deserialization. In the heterogeneous context, the which site will hold the copy. Moreover, the distributed receiver side is different from one site to another, and thus environment may hold different types of databases adding the deserialization implementation may vary depending on another level of complexity to the synchronization process.

This data serialization is a very sensitive the near real-time duplication process, the synchronization task that may speed down the synchronization process and delay is a crucial criterion that may change depending on flood the network.

    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.
