For some reasons when we delete a MergeTree Part in atomic way something may go wrong - and leave the `delete_tmp_*` folder or it's part on disk. This may lead to a disk space consumption over time.

It's suggested to delete this folders at least at server start-up. Current solution with `clearOldTemporaryDirectories()` doesn't work because this method is called periodically from a thread without any locks or advisory on folders - it may cause the race conditions.
{
    auto lock = lockParts();
    for (const auto & part : parts)
    {
        
        part->assertState({DataPartState::Deleting});
        modifyPartState(part, DataPartState::Outdated);
    }
}
void MergeTreeData::removePartsFinally(const MergeTreeData::DataPartsVector & parts)
{
    {
        auto lock = lockParts();
        
        for (const auto & part : parts)
        {
            
            if (part->getState() == DataPartState::Temporary)
                continue;
            auto it = data_parts_by_info.find(part->info);
            if (it == data_parts_by_info.end())
