Hello, mod_perl users, TL;DR: which Perl-based solution would you recommend for serving long-term HTTP connections?
We use mod_perl for our project, and we would like to add a component which needs long-term connections (think websockets or server-side-events https://developer.mozilla.org/en-US/docs/Web/API/Server-sent_events/Using_server-sent_events). We use mpm_prefork for the main site, so adding long-term connections there is not feasible. So I am looking for alternatives. The logic behind this application would probably not be overly complicated, probably just forwarding pub/sub events from Redis or some other message broker to HTTP clients or something like that. I would expect to serve about 30-100k simultaneous connections, not necessarily handled by a single host. The peak value of 10k connections per host would be sufficient. I expect I will put haproxy or some other load balancer in front of these servers, so for example SSL/TLS is not strictly necessary. Is mod_perl with mpm_worker suitable for this task? Or should I use something AnyEvent-based, such as Twiggy (I don't know whether Twiggy supports multiple processes/threads)? Or even something completely different? Thanks in advance for any recommendations. -Yenya -- | Jan "Yenya" Kasprzak <kas at {fi.muni.cz - work | yenya.net - private}> | | http://www.fi.muni.cz/~kas/ GPG: 4096R/A45477D5 | We all agree on the necessity of compromise.
