Do you use beam's hot-reload/recompilation in production?
Do you use hot-reload/recompilation in production?
Please note that this poll is only about BEAM’s internal features of runtime upgrades and recompilation. External tools for 0-downtime upgrade and deploys are out of the scope of this poll
- Yes, I regularly upgrade my system in production using relup/appup
- Yes, I regularly upgrade my system in production using some in-house solution which uses BEAM’s internal hot upgrade feature in runtime.
- Yes, I regularly upgrade my system using plain git pull && recompile
- Yes, when some bug occurs I prefer to fix the bug using recompile
- Yes, but only when a critical bug occurs
- No, I always upgrade running system using external tools
Sidenote:
If you do not use runtime recompilation, I’d like to discuss why and what do you use instead.
Personally, I used to work in a project where we used relup for publising patch version hot upgrades. However, it required a special technique to write code and relup testing pipeline was exotic

I used hot deploys extensively at my prior job. I wrote up my thoughts on it a while back (Why Hot Deploys are Cool | Greg Vaughn’s Musings). The landscape has changed in the past couple of years with distillery no longer being the primary tool to build releases though.

Voted “No”. I don’t care about the hot-upgrade thing and I pray I never need it.
But even if you end up needing it, IMO just having blue-green deployments with a load balancer is good enough.

No, but I am interested. I have an app that have internal state that taking many network loads and significant time to recover.
