EXPORT DATABASE CONFIGURATION

Description

The EXPORT DATABASE CONFIGURATION syntax is used to export storage units and rule configurations to YAML format.

Syntax

  1. ExportDatabaseConfiguration ::=
  2.   'EXPORT' 'DATABASE' 'CONFIGURATION' ('FROM' databaseName)? ('TO' 'FILE' filePath)?
  4. databaseName ::=
  5.   identifier
  7. filePath ::=
  8.   string

Supplement

  • When databaseName is not specified, the default is the currently used DATABASE. If DATABASE is not used, No database selected will be prompted.

  • When filePath is not specified, the storage units and rule configurations will export to screen.

Example

  • Export storage units and rule configurations from specified database to specified file path
  1. EXPORT DATABASE CONFIGURATION FROM test1 TO FILE "/xxx/config_test1.yaml";
  • Export storage units and rule configurations from specified database to screen
  1. EXPORT DATABASE CONFIGURATION FROM test1;
  1. mysql> EXPORT DATABASE CONFIGURATION FROM test1;
