EXPORT DATABASE CONFIGURATION

Description

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

Syntax

ExportDatabaseConfiguration ::=
  'EXPORT' 'DATABASE' 'CONFIGURATION' ('FROM' databaseName)? ('TO' 'FILE' filePath)?

databaseName ::=
  identifier

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