Subject Re: is flink' states functionality futile?
Date Sun, 23 Jul 2017 05:50:37 GMT
Ok, Let me see if I understand you correctly. 
You actually state that flink' states functionality is introduced only to
handle recovering from failures. 
Let's take the example given in 1.3 documentary - 
it's a program that sinks messages only after enough items accumulated in
the buffer. 
Now, assume I'm not bothered of recovering failures and only want the
simplest way to implement a program that remembers data from the last run in
the stream, then, according to you, I may not use none of the elements
associated with flink' states - 
and the program still functions correctly?
