MySQL 5.7 Reference Manual  /  ...  /  Server Plugins Available

5.5.1 Server Plugins Available

MySQL distributions include several plugins that implement server extensions:

  • Plugins for authenticating attempts by clients to connect to MySQL Server. Plugins are available for several authentication protocols. See Section 6.3.8, “Pluggable Authentication”.

  • A connection-control plugin that enables administrators to introduce an increasing delay after a certain number of consecutive failed client connection attempts. See Section 6.5.2, “The Connection-Control Plugins”.

  • A password-validation plugin implements password strength policies and assesses the strength of potential passwords. See Section 6.5.3, “The Password Validation Plugin”.

  • Group Replication enables you to create a highly available distributed MySQL service across a group of MySQL server instances, with data consistency, conflict detection and resolution, and group membership services all built-in. See Chapter 17, Group Replication.

  • MySQL Enterprise Edition includes a thread pool plugin that manages connection threads to increase server performance by efficiently managing statement execution threads for large numbers of client connections. See Section 5.5.4, “MySQL Enterprise Thread Pool”.

  • MySQL Enterprise Edition includes an audit plugin for monitoring and logging of connection and query activity. See Section 6.5.5, “MySQL Enterprise Audit”.

  • MySQL Enterprise Edition includes a firewall plugin that implements an application-level firewall to enable database administrators to permit or deny SQL statement execution based on matching against whitelists of accepted statement patterns. See Section 6.5.6, “MySQL Enterprise Firewall”.

  • A query rewrite plugin examines statements received by MySQL Server and possibly rewrites them before the server executes them. See Section 5.5.5, “The Rewriter Query Rewrite Plugin”

  • Version Tokens enables creation of and synchronization around server tokens that applications can use to prevent accessing incorrect or out-of-date data. Version Tokens is based on a plugin library that implements a version_tokens plugin and a set of user-defined functions. See Section 5.5.6, “Version Tokens”.

  • Keyring plugins provide secure storage for sensitive information. See Section 6.5.4, “The MySQL Keyring”.

  • X Plugin extends MySQL Server to be able to function as a document store. Running X Plugin enables MySQL Server to communicate with clients using the X Protocol, which is designed to expose the ACID compliant storage abilities of MySQL as a document store. See Section 19.7, “X Plugin”.

  • Semisynchronous replication plugins implement an interface to replication capabilities that permit the master to proceed as long as at least one slave has responded to each transaction. See Section 16.3.9, “Semisynchronous Replication”.

  • Test framework plugins test server services. For information about these plugins, see Plugins for Testing Plugin Services.

The following sections describe how to install and uninstall plugins, and how to determine at runtime which plugins are installed and obtain information about them. For information about writing plugins, see Section 28.2, “The MySQL Plugin API”.
