The keywords you’re looking for are “fullya-concurrent” or “on-the-fly” GC, but I’m not aware of any production runtime with those.
- WJW 4y agoDoesn't the JVM ecosystem have fully concurrent GC with the Azul C4 collector? It's not my favorite set of languages but I don't think we can realistically claim the JVM is not a production-ready runtime.
- tomp 4y agoYes, "pauseless" is another keyword I forgot to mention. Azul uses a read barrier which I guess makes it so slow that noone uses it (and the same ideas haven't made their way into JDK collectors). The previous version required hardware-supported read barrier, now AFAIK they only require a Linux kernel extension.
