Exactly, it's similar to Linux live kernel patching. It's certainly desirable, but with the support of modern orchestration platform, most of the time it's simpler to migrate services off the nodes, update, reboot then redeploy.
- toast0 3y agoHaving worked with hot loading for a long time, and now working without, even if you bring up new nodes, migrate services, destroy old nodes, it just takes so much longer, and you have to spend so much more time dealing with the multiple versions at once problem. Especially if you have state in your service. Shutting down servers with active clients is disruptive, and moving clients immediately is difficult. Simple HTTP request/response is easier, but a lot depends on your load balancing.
