Going through the changelogs of recent versions I found that support for multiple AR databases is now supported out of the box! 🎉

I tried to change our setup which was based on span preprocessors to use the new databases: option when configuring Rails. Unfortunately, I was not able to get it to work and everything was tracked in the database service specified as database_service.

My configuration was something like this:

    c.use :rails,
      database_service: 'main-db',
      databases: {
        archive: { service_name: 'archive-db' },
        follower: { service_name: 'follower-db' }
      }

I tried to find how databases: is applied but I was not able to find the right spot. (I was mainly looking at framework.rb)

Would you be able to give me a hint where I can follow-up to get this working? Thanks a lot in advance and great work on the rapid pace of new features!
