Rather than thinking of this as an any to any comparison with the exponential growth that can result,designate one machine as the 'master' and have it send it's table to the other 6 (n) machines, that simply update/replace their copy from the master.

No comparison necessary. A straight delete and replace of the table is going to be much quicker than a (multi-way) comparison.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
Lingua non convalesco, consenesco et abolesco. -- Rule 1 has a caveat! -- Who broke the cabal?
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
