the main point remains: -why would you process a TB file on a wimp "laptop" machine? -where does this file come from? -why wouldn't this be a DB report?
  1. The OP has made no mention of "laptop".
  2. None of you trucking business :)
  3. It would take 10x the disk storage and 20x longer just to load this data into the DB.

    Never mind how long it would take to process the query, returning a billion counts, serialised through a socket or pipe, to an application program.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
