Rails: Moving from Active Record Session Store to a Redis Store


gqlewis
HOME ยป Programming Languages

I have a large application that as many, many thousand active sessions. I want to migrate into a Redis session store using this. And ideally, I want my current sessions to stay active.


Does anyone have any experience in migrating active sessions. I assume I write either a migration or a rake task (I think migration, so I can drop the old table as part of this), and I want to just write into redis all the current details.


old_sessions = ActiveRecord::Base.connection.select_all("select * from sessions")
old_sessions.each { |session| $redis.set(????? ????) }

But I am worried about data integrity.

I've been asked to use Redis, but I'm wondering if it is a good ideas because I've heard that Redis delays write operations, so I'm a bit afraid because sessions needs to be real times.



Using Redis as the primary Rails store
by PeterYunZhang in Programming Languages

How can I use Redis as the primary data store for a Rails app, and omit the SQL db? Is there an ORM / adapter that can translate Rails models into Redis objects in the same seamless manner as the SQL adapters / ActiveRecord ?
