Subject [Structured Streaming] How to compute the difference between two rows of a streaming dataframe?
Date Sat, 30 Sep 2017 02:44:02 GMT
Hi,

I want to compute the difference between two rows in a streaming dataframe,
is there a feasible API? May be some function like the window function *lag
*in normal dataframe, but it seems that this function is unavailable in
streaming dataframe.

Thanks.
