Hi, 15155. May I clarify a couple of things? 1. Regarding Python's GIL: The issue isn't memory sharing between threads. Java and Go allow you to do this, too, but they don't have GILs. The reason Python has a GIL is that it uses reference counting for memory management. If it didn't have a GIL, multiple threads could simultaneously manipulate reference counts, which would lead to memory corruption/leaks. 2. You can share massive "objects" between BEAM processes. For example, if you're running BEAM in a 64-bit environment, you can share maps, structs, and other data structures that are up to 2,305,843,009,213,693,951 bytes in size. I hope this information helps. I also hope it is correct. I think it is, but I've been wrong before. |
