Certain MySQL Server plugins and components are loaded in the DB system automatically. You do not need to install any of these plugins.

• MySQL Enterprise Thread Pool: The thread pool plugin provides an alternative thread-handling model designed to reduce overhead and improve performance. See MySQL Enterprise Thread Pool.
• MySQL Enterprise Audit plugin: The audit plugin enables MySQL Server to produce a log file containing an audit record of server activity. The log contents include when clients connect and disconnect, and what actions they perform while connected, such as which databases and tables they access. You can add statistics for the time and size of each query to detect outliers. You cannot change the default values of the plugin.
  • audit_log_buffer_size: 10485760
  • audit_log_compression: GZIP
  • audit_log_database: mysql_audit
  • audit_log_file: /db/audit/audit.log
  • audit_log_flush_interval_seconds: 60
  • audit_log_format: JSON
  • audit_log_format_unix_timestamp: ON
  • audit_log_max_size: 5368709120
  • audit_log_prune_seconds: 604800
  • audit_log_rotate_on_size: 52428800
  By default, audit plugin logs are disabled, and you have to define filters to enable logging all auditable events for all users. See Defining Audit Plugin Filters. By default, there are few global privileges granted and few privileges revoked from the mysql_audit schema. See Default MySQL Privileges, and MySQL Enterprise Audit Plugin.
• The connection_control plugin: MySQL Server includes a plugin library that enables administrators to introduce an increasing delay in server response to connection attempts after a configurable number of consecutive failed attempts. The default value of the variables of the connection-control plugin are as follows, and you cannot change the default values:
  • connection_control_failed_connections_threshold : 3
  • connection_control_max_connection_delay: 10000
  • connection_control_min_connection_delay:1000
  See Connection-Control Plugins.
• The validate_password component: The component serves to improve security by requiring account passwords and enabling strength testing of potential passwords. The default value of the variables of the validate_password component are as follows, and you cannot change the default values:
  • validate_password.check_user_name: ON
  • validate_password.length: 8
  • validate_password.mixed_case_count:1
  • validate_password.number_count:1
  • validate_password.policy: MEDIUM
  • validate_password.special_char_count :1
  See Password Validation Component.
• Data masking: The general-purpose masking functions mask arbitrary strings, special-purpose masking functions mask specific types of values, and generate functions generate random values. See Data Masking.
