Message msg = MessageBuilder().setContent("repl").disableReplication(true).build();
```
3. Producer create connect in cluster C and send ```Message msg```
```
producer.sendAsync(msg, notifySendMessage);
```
**Actual output is consumer**
1. Cluster A
```
Received message: repl
```
2. Cluster A
```
Received message: repl

Research direction

Start by tracing MessageBuilder.disableReplication(true) through the C++ client and the producer.sendAsync path, using the three-cluster geo-replication steps to reproduce the behavior. Done means a message sent from cluster C remains in C and is not received by clusters A or B when replication is disabled.
