The scheduling module allows you to create a time schedule for operations you need to trigger in a repetitive or timely manner.
Similar to cron from Unix systems, each schedule represents a separate time schedule definition and a task to perform.
In Cluster, you can explicitly specify which node should execute the scheduled task using the Nodes to process parameter. However, if not set, the node will be selected automatically from all available nodes (but always just one).

Tasks you can schedule are described in Chapter 28, Tasks.
