 * Clickhouse cluster mode is not officially supported, since it's not tested right now, but you can try enabling `schema_migrations` table replication by specifying a `x-cluster-name`:
   * When `x-cluster-name` is specified, `x-migrations-table-engine` also should be specified. See the docs regarding [replicated table engines](https://clickhouse.tech/docs/en/engines/table-engines/mergetree-family/replication/#table_engines-replication).
   * When `x-cluster-name` is specified, only the `schema_migrations` table is replicated across the cluster. You still need to write your migrations so that the application tables are replicated within the cluster.
-* If you want to create database inside the migration, you should know, that table which will manage migrations `schema-migrations table` will be in `deafault` table, so you can't use `USE <database_name>` inside migration. In this case you can not specify the database in the connection string (example you can find [here](examples/migrations/003_create_database.up.sql))
