Examples of org.jboss.dashboard.dataset.DataSetSettings

org.jboss.dashboard.dataset.DataSetSettings
Sometimes, the nature and location of data may lead to unexpected bad performance situations like: high-volume data load or connectivity issues. To cope with these situations the system needs detection mechanisms.
This interface defines a bunch of settings that the system uses to know what are the thresholds allowed for some data set operations like: load, filter or group. Such operations are cpu or memory intensive prone and could compromise the system stability.
