What would it take to get this demo working with postgres? about async-rails

[kashif]

i suspect to get it working with postgresql one would need to get the em_postgresql working with rails 3 as you rightly pointed out. The em_postgresql is using the postgres-rb pure ruby drivers which implement many but not all of the async api's to postgresql, so one would need to get that done first I suspect. I have forked the two projects and am in the process of updating them... but can not afford too much time to it, but any help would be great.

John, unfortunately don't have hands on experience with the PG driver, but in theory, as long as there is a working async PG adapter for ActiveRecord 3.x, then it should be no different from the mysql example with the mysql2 gem.

Have you tried running it with em-postgres driver? This thread may help: mperham/em_postgresql#1

Thanks for your reply. (you're my hero by the way, I'm a big fan of all the cool performance related stuff you do)

I did read through that thread earlier today, (I should have included that in my original post) and I spent a good chunk of time today trying to get the em_postgresql driver to work with your asyc_rails project. I'll continue the discussion on that thread, as that's where the real issue lies.

Sounds good. Let me know what you find, I'm sure there are others looking for same information..

There's another—unrelated to Perham's—em-postgresql-adapter for ActiveRecord 3: leftbee/em-postgresql-adapter

It works with Rails 3.0.x but not 3.1.

em-postgres-adapter has been fixed to work with AR 3.1

Awesome! Added a link to the driver in the readme, closing this bug -- woohoo! ;-)
