Zoltan Haindrich updated HIVE-23806:
------------------------------------
Description:
in case there are many partitions; adding a new column without cascade may take
a while - because we want to make sure in schema evolution cases that we don't
reuse stats later-on by mistake...
however this is not neccessary in case the schema is extended
> Avoid clearing column stat states in all partition in case schema is extended
> -----------------------------------------------------------------------------
