Highest sustained spinning rust write speed to date on a box

Yeah … the day job hardware. Current generation. Single box. Single thread. Single file system.

`Run status group 0 (all jobs):
  WRITE: io=130692MB, aggrb=4702.9MB/s, minb=4815.8MB/s, maxb=4815.8MB/s, mint=27790msec, maxt=27790msec

There is a name for my pain this evening. InfluxQL.

'select "*" from newdb where my_left_arm = twisted_behind_back AND ...'

SYNTAX ERROR: your arm must be broken for this query to work

My gosh ... I've got 30 year old perl code that uses shelling of that time, and still runs.

This ... isn't a win.

That, and I really miss the ease of

if ($var =~ /regex/) {

}

blocks. No real equivalent in Py. Lots more boilerplate around using regex. /sigh

Code works perfectly in Py3.9. Breaks in Py3.6. Looks like subprocess semantics are different between the two.

Just ... wow.

I could say bad things about the language. But the point of using these scripting languages is speed of development without much defensive coding.

(looks around on the interwebs for a cluster top like thing for slurm, doesn't find one, and resists the urge to write his own ...)
