Re: [HTCondor-users] File last modification time or job last write() attribute?

[Iain Bradford Steers <iain.steers@xxxxxxx>]

Thereâs also a delayed set available via the condor_chirp utility.

Gets back to the schedd with a maximum of 15-minutes delay IIRC.

The inotify idea is interesting, though I would definitely see scalability
challenges with that approach. Wouldn't want to chirp on every write, that's
for sure. The 5-minute interval of the update_job_info hook seems
like it would address scalability concerns but still keep enough
granularity to make the data useful in expressions. But being able to do
it without occupying the HookKeyword would be handy too.

Thanks for the suggestion!
