Appendix F. Additional Replication High Availability Configuration Elements
The following table lists additional ha-policy configuration elements that are not described in the Configuring replication high availability section. These elements have default settings that are sufficient for most common use cases.
| Name | Used in | Description |
|---|---|---|
| check-for-live-server | Embedded broker coordination |
Applies only to brokers configured as master brokers. Specifies whether the original master broker checks the cluster for another live broker using its own server ID when starting up. Set to |
| cluster-name | Embedded broker and ZooKeeper coordination | Name of the cluster configuration to use for replication. This setting is only necessary if you configure multiple cluster connections. If configured, the cluster configuration with this name will be used when connecting to the cluster. If unset, the first cluster connection defined in the configuration is used. |
| initial-replication-sync-timeout | Embedded broker and ZooKeeper coordination |
The amount of time the replicating broker will wait upon completion of the initial replication process for the replica to acknowledge that it has received all the necessary data. The default value of this property is NOTE: During this interval, any other journal-related operations are blocked. |
| max-saved-replicated-journals-size | Embedded broker and ZooKeeper coordination |
Applies to backup brokers only. Specifies how many backup journal files the backup broker retains. Once this value has been reached, the broker makes space for each new backup journal file by deleting the oldest journal file. The default value of this property is |
