Table 22.2. Optional properties - these properties aren't vital for cluster configuration - default values are sufficient
| property | type | default | description |
|---|---|---|---|
| cluster.node.sendinfo.interval | int | 5000 | time interval in ms; each node sends info about itself to another nodes; this interval specified how often the info is sent |
| cluster.node.remove.interval | int | 15000 | time interval in ms; if no node info comes in this interval, node is considered as lost and it is removed from the cluster |
| cluster.max_allowed_time_shift_between_nodes | int | 2000 | Max allowed time shift between nodes. If time shift exceeds this, node will be selected as invalid. |
| cluster.group.name | String | cloverCluster | Each cluster has its unique group name. If you need 2 clusters in the same network environment, each of them would have its own group name. |
| cluster.max_allowed_time_shift_between_nodes | int | 2000 | How many miliseconds is maximum allowed time shift between nodes in the cluster. All nodes must have system time synchronized. Otherwise cluster may not work properly. So if this threshold is exceeded, node will be set as invalid. |
