Fact History Load is taking quite huge time in Synapse

Uma B 1 Reputation point

Hi Team ,

I am trying to load Fact Table (1.8Millions data) needs to be loaded as part of History Load.
first when I tried it took 14+ hours and then it got failed.
So then i tried to do partial load for each year. which i was able to quite well from 2015 to 2020 but now loading for current year it is taking quite hell lot of time(almost 4 + hours still not completing)
in query plan when i checked it is showing some 30billions estimated rows, also shuffling is happening

I have updated all statistics.

I have already raised Microsoft ticket regarding this but i have not received proper response from there.

Can some one assist me here ?
