Web Sockets in Tornado. Bret Taylor has a simple class making it trivial to experiment with the Web Sockets protocol (now shipping in Chrome) using the scalable Tornado application server. He also raises the million dollar question: what will existing load balancers and proxies make of the new protocol? # 31st December 2009, 11:54 am
Tornado Web Server (via) An extremely exciting addition to the Python web landscape, Tornado is the open sourced version of FriendFeed’s custom web stack. It’s a non-blocking (epoll) Python web server designed for handling thousands of simultaneous connections, perfect for building Comet applications. The web framework is cosmetically similar to web.py or App Engine’s webapp but has decorators for writing asynchronous request handlers. The template language uses Django-style syntax but allows you to use full Python expressions. FriendFeed have benchmarked it handling 8,000 requests a second running as four load-balanced processes on a 4 core server. # 10th September 2009, 9:32 pm
How FriendFeed uses MySQL to store schema-less data. The pain of altering/ adding indexes to tables with 250 million rows was killing their ability to try out new features, so they’ve moved to storing pickled Python objects and manually creating the indexes they need as denormalised two column tables. These can be created and dropped much more easily, and are continually populated by an off-line index building process. # 27th February 2009, 2:33 pm
