Change the table comment after created the table is not supported now?
Like mysql : ALTER TABLE [tableName] COMMNET [comment]; 
The sql "ALTER TABLE `system`.tables UPDATE Comment='test' WHERE NAME='t1';" also not supported!!!
My version is '21.9.4.35'。
{
    for (const DiskPtr & disk : data_volume->getDisks())
    {
        disk->createDirectories(new_path_to_table_data);
        disk->moveDirectory(relative_data_path, new_path_to_table_data);
        auto new_path = disk->getPath() + new_path_to_table_data;
        LOG_DEBUG(log, "Updating path to {}", new_path);
        std::lock_guard lock(cluster_nodes_mutex);
        for (auto & node : cluster_nodes_data)
            node.second.directory_monitor->updatePath(new_path_to_table_data);
    }
    relative_data_path = new_path_to_table_data;
}
