Can we able to calculate SPICE dataset size

Hello Akshay,

Fist of all Welcome to the QuickSight Community.

I would recommend first of all to understand what exactly is SPICE and how it works.Importing data into SPICE - Amazon QuickSight

Estimating SPICE -Importing data into SPICE - Amazon QuickSight

Managing SPICE capacity -Managing SPICE memory capacity - Amazon QuickSight

There is no retention period or Expiry of Data set. It remains unless you delete it it.

Hope this helps.

Cheers,
Deep
