Renaming an Index

DSC supports renaming indexes. Prefix a table name to an index name to prevent name conflicts. (Only DDL statements with specific index names can be created. Currently, the name of a renamed index cannot be deleted. Exercise caution when modifying this parameter.)

Modifying the configuration

Open Table 1 Configuration parameters in the features-mysql.properties file and change the value of the following parameter to true: The default value is false, indicating that the file will not be renamed.
