Deploying CDL for Geo Replication (GR)
For Geo Replication (GR), you have to create two separate HA systems independently and configure the Geo HA for communications with the remote sites. By default, CDL is deployed with two replicas for db-ep, one slot map (with two replicas per map) and one index map (with two replicas per map).

|
To deploy the CDL GR, use the following configuration:
Procedure
Step 1 | Deploy HA on site-1. Deploy site-1 HA system without any Geo HA related configuration parameters and set the system-id parameter to 1 in the configuration.
Example:
|
Step 2 | Apply the HA configuration on site-1. Commit the configurations and deploy the pods on site-1. |
Step 3 | Deploy HA on site-2. Deploy site-2 HA system (in parallel) without any Geo HA related configuration parameters and
set the system-id parameter to
2 in the
configuration.
Example:
|
Step 4 | Apply HA configuration on site-2. Commit the configuration and deploy the pods on site-2. |
Step 5 | Verify whether site-1 and site-2 are active. Verify whether the CDL, Kafka, and Zookeeper pods are active before proceeding to Geo HA configuration. |
Step 6 | Configure external IP address on site-1 for site-2 communication. |
Step 7 | Configure external IP address on site-2 for site-1 communication. |
Step 8 | Add the remote site information in each of the sites. |
Step 9 | Verify whether Mirror Maker pod is deployed and all the other pods are active. NOTES:
