Indexes for MariaDB Xpand
MariaDB Xpand provides DDL (Data Definition Language) syntax to create, alter, or drop indexes:
Xpand performs many DDL operations as online schema changes, which allows concurrent reads and writes during the operation
Xpand's DDL syntax is very similar to the DDL syntax of MariaDB Enterprise Server and MySQL 5.7
In the context of ISO 9075-2:2016, this page uses "DDL (Data Definition Language)" to refer to SQL statements in the standard's "SQL-schema statements" group.
