   Thanks @goutamadwant  that will be amazing. -- I think the key here will be 
to break the work down into manageable pieces  (so that we can review it 
incrementally)
   
   I also suspect that in writing this you will uncover areas in need of 
additional features / cleanu, so we will have to be careful not to try and boil 
the ocean
   
   What I would suggest doing first, is creating an example in 
datafusion-examples of the simplest possible streaming system -- basically a 
program that shows how to feed rows into a streaming query (perhaps something 
like a filter) and shows how rows come out of it as you push rows in. 
   
   As I mentioned, I suspect this won't work great at first and well need to 
update some things (like the FilterExec) but starting with the example will 
help motivate that
   
   With that example, we cna then start writing a "Using datafusion for 
streaming" section in the library user guide 
https://datafusion.apache.org/library-user-guide/index.html
