zhangxinyu commented on SPARK-17631:
------------------------------------

I agree with your points that http could be used as a ligthweight protocol for 
transferring data to remote system, and `ForeachSink` can cover this function. 
However, http protocol is widely used, why http users have to implement it by 
themselves? Maybe it's better to use `HttpSink`, because users only need to set 
some configurations. Instead, if we use foreachSink, users have to implementing 
`ForeachWriter` themselves. 

About the second use case, i can't agree with you more. I should support https 
and add some configuration so that it can be more useful. Could you give me 
more examples about configurability?

Thank you so much!
