3* Drop command will not work on Cassandra 2.X because it rely on
4system_schema table which comes with 3.X
5* Other commands should work properly but are **not tested**
6* The Cassandra driver (gocql) does not natively support executing multiple statements in a single query. To allow for multiple statements in a single migration, you can use the `x-multi-statement` param. There are two important caveats:
7 * This mode splits the migration text into separately-executed statements by a semi-colon `;`. Thus `x-multi-statement` cannot be used when a statement in the migration contains a string with a semi-colon.
8 * The queries are not executed in any sort of transaction/batch, meaning you are responsible for fixing partial migrations.
