Last I heard Quartz and Athena are both failed projects. Quartz's lead left years ago, Netezza DB was having massive issues, and Python was way too slow. They had to reboot the project and it is nowhere close to what they wanted it. Athena has similar issues with developers constantly changing, no direction, and still isn't anywhere close to real-time risk. I know Credit Suisse had something working, but I haven't heard where that project was going since they moved it from C# to Java.
SecDB is still, even with its warts, the leader.
