h3. I have the same question. Here's the question I posed on stackflow [link
title|[apache spark - Why are spark3 dynamic partitions slow to write to hive -
Stack
Overflow|https://stackoverflow.com/questions/76997680/why-are-spark3-dynamic-partitions-slow-to-write-to-hive]]
This is one of my tasks, the code is almost the same adjusted part of the log
printing, respectively, using {{spark2}} (left) and {{spark3}} run (right), in
the case of the same parameters, {{spark3}} each job running speed are
significantly better than {{{}spark3{}}}, but the total running time {{spark3}}
spent 1.2h, while {{spark2}} only spent 44 min. Why this phenomenon occurs?
What is this extra time used for?[The top part is the eventTime forspark2 r,
and the bottom part is for a spark3]
