I saw the v8 description says: > Isolate <https://v8docs.nodesource.com/node-14.1/d5/dda/classv8_1_1_isolate.html> represents an isolated instance of the V8 <https://v8docs.nodesource.com/node-14.1/df/d43/classv8_1_1_v8.html> engine. V8 <https://v8docs.nodesource.com/node-14.1/df/d43/classv8_1_1_v8.html> isolates have completely separate states. Objects from one isolate must not be used in other isolates. The embedder can create multiple isolates and use them in parallel in multiple threads. An isolate can be entered by at most one thread at any given time. The Locker/Unlocker API must be used to synchronize.
According to my understanding, it seems one isolate can be run in multiple thread (not in same time), and multiple isolate can be managed in one thread. Because I want to use Isolate as the VM for my program in multi-tenant case, so I read some of the v8 API, I found that `v8::Isolate` has some APIs like: - `Isolate::enter`, `Isolate::exit` - `Isolate::TerminateExecution` - `Isolate::CancelTerminateExecution` - `Isolate::RequestInterrupt` So, is it possible to "schedule" massive isolates among multiple threads using v8 public APIs like above or does v8 support to achieve the "schedule" ? The "schedule" here means maybe: 1. work stealing: let a thread run an isolate which was created and init by other thread to balanced the isolate distribution. 2. round-robin: one thread created multiple isolate, when an special event happend (maybe recv an os signal), one of the running isolate could be paused the execution progress, save the execution context and switch into other isolate, after other isolate finished, resume the previous isolate's execution. -- -- v8-users mailing list v8-users@googlegroups.com http://groups.google.com/group/v8-users --- You received this message because you are subscribed to the Google Groups "v8-users" group.
