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 - https://ci.apache.org/projects/flink/flink-docs-release-1.3/dev/stream/state.html <https://ci.apache.org/projects/flink/flink-docs-release-1.3/dev/stream/state.html> 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 - ListState snapshotState initializeState restoreState and the program still functions correctly?
