This very, very simple app is just an attempt at showing the power of go routines / concurrent processing.
It calls 2 funcs, DoBigQuery() and DoBigQueryInARoutine()
As you'll see, it runs DoBigQuery() only 20 times, and DoBigQueryInARoutine() 50,000 times. They both call DoComplicatedComputeThingy() for the number that's passed into it.
DoComplicatedComputeThingy() simulated some kind of compute / transaction that'll take .2 seconds.
Clone the repo, ensure you've got go installed.
cd into the directory and run go run .
The output will be all of the calculations it's run from DoComplicatedComputeThingy() and then print the total time for sQ (serial query (no go routines)), and cQ (concurrent query (go routines)).
