Does it mean that the user needs to be aware of the "wrong" results and somehow also be able to tolerate a temporary wrong result in the user's application?
Just try to understand the scope of this improvement that can be applied to
- the downstream system must be an "upsert" system, in other words, when the system receives a new inserted value, it should overwrite the exist value in the system with the same key.
- the result of a specific will be "eventually correct" but maybe some key will lost for a while... (I think maybe there could be another solution when I write this. maybe we can delay the delete operation to achieve a better experience for user)
- the order of different key's update during a barrier is not guaranteed. And that's not guaranteed in our current implementation too.
