Thanks Roberto,
So we will have to split our code into different apps then.
We cannot just do something like that :
local function one()
--do something long running (5s)
return res
end
local function two()
--do something fast
return res
end
local c,d = one,two
-- here spawn means execute
local e = c.spawn
local f = d.spawn
-- here readState means read the result or wait for it until it is done.
e.readState()
f.readState()
That way we could run in parallel inside the same app.
Is this behavior possible ?
Thanks
