I have around 58,00,000 primarykeys in FILE1

Is that 5.8 million or 58 million or ... ?

And how many rows are there in your table?

I am going to work on multiple such FILES.

Do you mean pairs of files?

Ie. will each new query consist of a different FILE1 & FILE2? Or the same FILE1 with a different FILE2? Or vice versa?

In the absence of evidence, opinion is indistinguishable from prejudice.

The start of some sanity?
