GitHub user luky116 edited a discussion: 🙏  Topic data between clusters is out 
of sync in pulsar GEO mode

I used puslar's GEO for cluster replication and built a public zk as the 
configurationStore to synchronize the data between the two clusters. I found a 
problem. The steps are as follows, can someone do me a falvor 🙏 🙏 🙏 :


1. Suppose there are two clusters synchronizing data with each other, cluster1 
and cluster2; 
2. I create a Namespace in cluster1 named ns1, ns1 Only belongs to cluster1; 
3. Create a Topic under ns1, named topic1, and produce 100 messages to Topic1; 
4. Set ns1 to belong to cluster1 and cluster2 through the set-clusters command; 
5. 【Question 1 】At this time, you will find that topic1 does not exist in 
cluster2. This topic1
6. 【Question 2】We use the command to create topic1 in cluster2, and I am 
prompted that "topic1 already exists", so the creation failed.
