Hi ,

Can we create thread pool in openresty ?
So that when we spawn threads , it will first check if similiar thread exists in pool and if yes then resuse it.

Are you talking about OS threads or "light threads" (as created by
ngx.thread.spawn)?

Yes, there is plan to add a builtin pool for the Lua thread objects
for light threads. Patches welcome :)

BTW, are you seeing Lua thread creation and GC being hot in your
real-world setup? (For example, being hot in an on-CPU flamegraph
[1]).
