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'。

    std::filesystem::recursive_directory_iterator begin(dir_path);
    std::filesystem::recursive_directory_iterator end;
    for (auto it = begin; it != end; ++it)
    {
        const auto & file_path = it->path();
        if (!std::filesystem::is_regular_file(*it) || !endsWith(file_path.filename().string(), ".bin"))
            continue;

        try
        {
            num = parse<UInt64>(file_path.filename().stem().string());
        }
