Is it possible to use 'groupby' asynchronously?

[Frank Millman]

Hi all

I have used itertools.groupby before, and I love it. I used it to process a 
csv file and 'break' on change of a particular field. It worked very well.

Now I want to use it to process a database table. I can select the rows in 
the desired sequence with no problem. However, I am using asyncio, so I am 
reading the rows asynchronously.

My 'reader' class has __aiter__() and __anext__() defined.

If I pass the reader to groupby, I get the error message 'object is not 
iterable'.

Before I spend hours trying to figure it out, can anyone confirm if this is 
doable at all, or is groupby not designed for this.

Thanks
