Space consumed by Primary Index - response (4) by Nishant.Bhardwaj

Thanks Vlad for your response..
I belive that its size wont be fixed , the size of the Subtable is going to grow based on the data in main table.
for the tables which are currently in development database and going to production system,
then  in order to project how much space the table will take at prod, do we need to calculate the size of the secondary index subtable based on the no. of records in dev db.. for eg say for 1000 records the size comes out to be 0.5 GB ...
so we can use the same proportional increase in size at prod..
 
like 1000 records --> 0.5 GB
      10000 records --> 5 GB..
 
Is my understanding correct here?
 
Please correct or add some thing here..
cheers!
