"sleep for a couple of seconds"
But then you could only insert 1800 cdrs per hour...
If I was to insert 36000 cdrs per hour this means that I have to
open
parse
close
10 files per second. Imagine the I/O penalty just for opening - closing the
file.
(the persing is the same for both situations)

Not that you'd notice. We run XML CDR to database scripting on each box
that we use
for switching, and it's a pretty trivial task compared with switching
all that media. Doing it
this way is:-
(a) distributed - one process per box scales nicely;
(b) robust - script down, DB down, no problem: files just queue up;
(c) simple - the script logic is trivial:
- while 1
- for each file in the XML CDR directory
- open it
- parse it (XML::Simple for us)
- insert it in to the DB
- delete it
- sleep for a couple of seconds
Two error cases: can't parse or can't find data which should be there:
move the file in to
another directory to be examined by real eyes; DB insert fails: break
out of inner loop and
it'll be retried after a short pause.
