Hot swapping support in Erlang is first class, but even with that, it is not an easy feat to accomplish in large systems. Which is why, in my experience, people tend to avoid it if they can do without it. Systems i have worked with either had scheduled downtime periods or one could easily take down a node for upgrades without impacting the general availability of the system. In such cases, there is no real incentive to invest time and energy in managing hot swapping. But if you absolutely need all parts of your system be up 24/7, Erlang has the best story I've heard so far. |
