We're happy to say that we recently released the code for the TraceView Ruby instrumentation on Github as Open Source. There are a ton of benefits for AppNeta (and the community) in doing this so making the decision was easy... but the process of actually opening the repository and still keeping a few things private was slightly trickier. Here's the route we took that has worked out really well.

The Situation and Strategy

The Ruby instrumentation has always been sheltered on Github - albeit always in a private Github repository. We used the issues, pull requests and wiki pages extensively for everything from new employee resources to hosting screenshots, customer issues, internal discussions and links to other project and management tools (e.g. Asana).

Outside of the commits and the code, everything else was either of little use to the public or potentially company or customer confidential - stuff that shouldn't or couldn't be shared publicly. So this put us

Turning PostgreSQL into a queue serving 10,000 jobs per second

RDBMS-based job queues have been criticized recently for being unable to handle heavy loads. And they deserve it, to some extent, because the queries used to safely lock a job have been pretty hairy. SELECT FOR UPDATE followed by an UPDATE works fine at first, but then you add more workers, and each is trying to SELECT FOR UPDATE the same row (and maybe throwing NOWAIT in there, then catching the errors and retrying), and things slow down.

On top of that, they have to actually update the row to mark it as locked, so the rest of your workers are sitting there waiting while one of them propagates its lock to disk (and the disks of however many servers you're replicating to). QueueClassic got some mileage out of the novel idea of randomly picking a row near the front of the queue to lock, but I can't still seem to get more than an an extra few hundred jobs per second out of it under heavy load.

So, many developers have started going straight t
