>
> Hi, we using hive 3.1.1
> Currently in our hive have tables with hundreds of partitions and hundreds of
> gigabytes of data.
> When updating the column information of the corresponding table, it was
> confirmed that the performance was several tens of times slower than the Hive
> 1.1 version of the older CDH.
> I would like to ask if there is any architectural change that makes column
> updates slower than Hive 1 in Hive 3 and later versions.
> Thank you.
