The list includes the following principles −. piD = spawn(Fun) Erlang Scheduler Details and Why It Matters. There are some underlying features that make Erlang a soft real-time platform. One of them is its Garbage Collection mechanism which I talked about it in my previous article, Erlang Garbage Collection Details and Why It Matters. The other one is its scheduling mechanism that is well worth looking at.
