Connections – Mass file removal

I got a request to cleanup some files in a IBM Connections environment. Remove all the files created before 1.1.2015.
Getting the list of files is easy.

connect to files@
export to files.csv of del modified by nochardel
select hex(ID), id, title,create_date from files.media where create_date < date('2015-01-01')@ connect reset@
This got me around 11'000 records.
In the api documentation I found the required API call.
After a while I got my first node.js app. Which was correctly posting the required requests against my server. Doing a testrun with 11'000 records was a bad idea. My environment was so fast, that it sent the 11'000 requests in under 10s.
The first couple of request passed, but then I got a lot of errors and the files app did not respond at all. With the help of simple rate limiter I throttled it down to 2 requests/per second. The process will now take a bit longer, but at least the connections environment stays alive.
