Motivation
How to implement exactly once? Pulsar provides an implementation based on sequenceid, which requires users to maintain the mapping relationship between sequenceid and MSG. This requires development costs for users。
User data often has some characteristics, such as time, location, etc. we want to provide a way to convert the mapping relationship between maintenance sequenceid and MSG into the mapping relationship between data characteristics and MSG, so as to reduce user development costs.
