I worked on a project that used elixir without OTP. There’s a lot of nice things that elixir gives you and I didn’t personally feel like there was a significant learning curve. OTP is used under the hood for lots of analytics and reporting things, but those pieces were built by other people. The project I was working on had very specific requirements for response times that simply weren’t realistic with Ruby. We could have squeezed Ruby a bit to get what we needed, but it would have introduced complexity. We also knew we’d need to add features in the future while maintaining the same performance, so siding with the simpler solution made more sense to us. At some point in the near future we’ll probably use OTP, and I’ve already got a few ideas of how we’ll be leveraging it for some of our upcoming features. OTP is the killer feature, but I find working with elixir in general to be a very pleasant experience even on projects that don’t use it.
