hi,  
we are trying the sizing strategy for our elasticsearch implementaiton.

in general, if we have 5 TB worth of data to be indexed, how much would the index size be in total? Assuming both best-case index settings and worst-case index settings?

thanks,

Impossible to know.

But it's super easy to test it out.
