This doc demonstrates how to do geo-replication across multiple pulsar clusters without a global configuration store (zookeeper).
This demo is using docker-compose to start 3 pulsar clusters. Each pulsar cluster has 1 zk, 1 bk, and 1 broker. The docker compose file can be found at https://gist.github.com/sijie/63737459112471a82957ae20bd78adb5.
The information of all the three clusters is listed in the following table:
| zk | configuration store | broker | |
|---|---|---|---|
| beijing | zk-beijing | zk-beijing | broker-beijing |
| ------------------------- MODULE GryadkaCasRegister ------------------------- | |
| EXTENDS Integers, Sequences, FiniteSets | |

| \* Timestamps is the set of possible timestamps for operations to choose from. | |
| \* Each operation uses a unique timestamp. | |
| \* Values is the set of possible values to set the register to. | |
| \* Acceptors is the set of nodes which act as acceptors in the paxos sense. | |
| \* Quorums is the set of all possible quorums, typically simple majorities. | |
