>
> When a dimension (user_id) is accurately calculated at the same time, the
> original data is in the order of millions, and the rowkey has the encoding
> type fixed_lengrh and length 100. It took a few hours or even failed in the
> build dimension dictionary step. After investigation, it was found that there
> are concurrent processes that want to obtain the lock corresponding to the
> cube / dict path, resulting in a deadlock.
