CPAN Testers: Too much of a good thing right now

CPAN Testers has been growing by leaps and bounds lately and there have been some nice developments:

Unfortunately, this success has come at a cost. The Perl NOC, which provides the backend for CPAN Testers, is now deluged with reports. Reports are sent via email, each of which gets run through spam scanning and then archived on a filesystem and made available via NNTP.

This might have seemed like a practical design when there were only a few tens of thousands of reports and only a few hundred new ones coming in each month, but it no longer scales to what CPAN Testers needs. Worse, it puts a strain on the NOC to keep everything else running while managing the growing volume.

I've posted an alert to the CPAN Testers discussion list asking people to throttle their smoke testers for a while. The Perl NOC has given us a deadline of March 1 to launch CPAN Testers 2.0 and get off email/NNTP once and for all.

In the new year, I'll be posting more about a plan to make this happen.

What can be done quickly won’t replace all of the CT1.0 ecosystem right away but just the core transport and report repository parts. [...]
