Ilya Kasnacheev commented on IGNITE-7963:
-----------------------------------------

[~gvvinblade] please review amended fix, I've updated data sending behavior 
note.

> Futures from DataStreamer.addData() fail to complete if DataStreamer.flush() 
> is never called

> DataStreamer.addData() will return futures for operation.
> Thus the naive use of DataStreamer will look like this:
> {code}
> for (Data d : data)
>      futs.add(dataStreamer.addData(d));
> for (IgniteFuture f : futs)
>     f.get();
> dataStreamer.close();
> {code}
> However, this does not work. Unless flush is called (manual or otherwisE), 
> futures are not being processed. This code will likely hang on f.get().
> The solution, IMHO, is to introduce dataStreamer-flushing clause in f.get().
