Even without accounting for the sizeable overhead of spawning an OS process that, on average, twiddles its thumbs for a minute before reporting that no one has sent the user a message, the waiting time could be spent servicing 60-some requests for regular Facebook pages.The result of running out of Apache processes over the entire Facebook web tier is not pretty, nor is the dynamic configuration of the Apache process limits enjoyable.Cache misses and database failure can be detected by the non-database layers and either reported to the user or worked around using replication.While this architecture works pretty well in general, it isn't as successful in a chat application due to the high volume of long-lived requests, the non-relational nature of the data involved, and the statefulness of each request.I went to school for 7 years and was so busy with work and academics that I didn't make any friends post High School. I didn't think I would meet anyone who was serious enough to build a friendship, but I was very wrong. Back when I was new to town, I was desperate to meet other women.I was unemployed and didn't really interact with anyone.
Since going open source a year ago (we had the gall to release it on April Fool's Day, 2007), the Thrift project has steadily grown and improved (with multiple iterations on the Erlang binding).We chose to simulate the impact of many real users hitting many machines by means of a "dark launch" period in which Facebook pages would make connections to the chat servers, query for presence information and simulate message sends without a single UI element drawn on the page.With the "dark launch" bugs fixed, we hope that you enjoy Facebook Chat now that the UI lights have been turned on.This isn't by any means a new technique: it's a variation of Comet, specifically XHR long polling, and/or BOSH.Having a large-number of long-running concurrent requests makes the Apache part of the standard LAMP stack a dubious implementation choice.
