Replication in Multices Operations

If you have multiple instances yue, usually to sincinesy, sincrnesses. How do you go about that? It's it's done asincnesly for efficiency. So the challenge in this case is, since it'sdone as inconously, you don't know if the replication apen by default. In release, you may want to say the specific keys. When i do the specific operations, i want to be sure that it has been replicated. The latency for the overroperation will be based on your application, a factor, right?
