Concurrent handling of lsp handlers #409

Open pgujjula opened 2 years ago

pgujjula commented 2 years ago

Hello!

Currently it seems that the lsp handlers are not executed concurrently, so only one can run at a time. Are there any workarounds for this, or any plans to make it possible to run the handlers concurrently?

Indeed, it's currently up to the user to manage scheduling if they want to. The simple example is single-threaded. You can look at the reactor example for a concurrent version, HLS does something similar.

I'm a bit dissatisfied with the situation indeed, and I'd like to figure out a way to make it easier to get a concurrent server, while leaving as much scheduling control as possible in the hands of the user...
