Subject does the flink sink only support bio?

Hi, all.

The invoke method of sink seems no way to make async io? e.g. returns Future?

For example, the redis connector uses jedis lib to execute redis
command synchronously:


Then it will block the task thread of flink waiting the network
response from redis server per command?! Is it possible for other
operators running in the same thread with sink? If so, then it would
block them too?

I know flink has asyncio api, but it seems not for used by sink impl?
