XtraDB Command Interface

This feature provides a table for use in the implementation of future command interfaces to XtraDB.

The feature currently contains only a test command.

mysql> select * from INFORMATION_SCHEMA.XTRADB_ADMIN_COMMAND;
+-------------------------------------------------------------------------------+
| result_message                                                                |
+-------------------------------------------------------------------------------+
| No XTRA_* command in the SQL statement. Please add /*!XTRA_xxxx*/ to the SQL. |
+-------------------------------------------------------------------------------+
1 row in set (0.00 sec)

mysql> select * from INFORMATION_SCHEMA.XTRADB_ADMIN_COMMAND /*!XTRA_HELLO*/;
+----------------+
| result_message |
+----------------+
