Add an AsyncWaitOperator. The order of output stream records may be reordered.

类型参数:

IN - Type of input record

OUT - Type of output record

参数:

in - Input DataStream

func - AsyncFunction

timeout - for the asynchronous operation to complete

timeUnit - of the given timeout

capacity - The max number of async i/o operation that can be triggered

返回:

A new SingleOutputStreamOperator.
