The only way to use this feature is to specify an empty database name in Distributed table definition, but then you get a warning:

```
CREATE TABLE `demo_loan_all` (...) ENGINE=Distributed(test_cluster_two_shards_different_databases, '', demo_loan_01568, cityHash64(id));

<Warning> StorageDistributed (demo_loan_all): Name of remote database is empty. Default database will be used implicitly.
```

    statuses.reserve(cluster_nodes_data.size());
    for (const auto & node : cluster_nodes_data)
        statuses.push_back(node.second.directory_monitor->getStatus());
    return statuses;
}
