Hi DianFu,
Thanks for your feedback of the FLIP.
About the mentioned question for the `getLatestRules`, IMO, this doesn't
need to rename into `getRuleChanges` because this method is used for getting
the total amount of the latest rules which has been updated once.
About the CEP.rule method, the CEP.dynamicPattern renaming is confusing
for users. The dynamic pattern only creates the PatternStream not the
DataStream. From the concept, a dynamic pattern is also a pattern, not contains
the PatternProcessFunction. If renaming the CEP.rule into CEP.dynamicPattern,
the return value of the method couldn't include the PatternProcessFunction,
only returns the PatternStream. I think the difference between the Rule and the
Pattern is that Rule contains the PatternProcessFunction, but the Pattern or
DynamicPattern doesn't contain the function.
