Hi, I wonder how to maintain state in ProcessElement. For example,
s4-core/src/test/java/org/apache/s4/wordcount/WordCountPE.java The variable "int wordCounter;" is used in onEvent() function and is reset to zero after the onEvent() function finishes. This is stateless. s4-core/src/test/java/org/apache/s4/wordcount/WordClassifierPE.java The variables "private int counter;" and "TreeMap<String, Integer> counts" are used in onEvent() function to keep total word count and word count for each word. This is stateful. I am confused about such behavior of ProcessElement. How do I turn on/off stateless if there is such option? Thanks in advance. -- Regards, Jiaan
