Review comment:
> If value is negative should we throw an error instead?
agree, about the error report , for that existing logic just using WARNING
level log, to keep logic consistence, the new logic use a LOG(WARNING) to
report the error.
>Also behavior is slightly different; In the old code, if value <= 0 it does
not change max_concurrency. Here it sets it to 0.
fixed, when value is negative the new logic will just throw a warning then
return.
