4 About Analytics Datasets

The term dataset refers to the in-memory cached and on-disk saved data for a statistic, and is presented as an entity in Analytics with administration controls. Datasets are automatically created whenever you view statistics in Open Worksheets. A dataset is not saved to disk for future viewing unless you archive it. See Statistics Actions.

The Analytics: Datasets BUI screen lists all datasets. These include open statistics that are being viewed in a worksheet (and as such are temporary datasets that disappear when the worksheet is closed), and statistics that are being archived to disk.

The following fields are displayed in the Datasets view for all datasets.

Table 4-1 Field Descriptions of Datasets

Field	Description
Status icon	See the next table.
Overhead	Low, medium or high performance impact of the dataset; see the next table. Also see Storage Performance Impact and Execution Performance Impact.
Name	Name of the statistic/dataset.
Since	First timestamp in dataset. For open statistics, this is the time the statistic was opened, which might be minutes earlier. For archived statistics, this is the first time in the archived dataset, which indicates how far back in the past this dataset goes, which might be days, weeks, months. Sorting this column shows the oldest datasets available.
On Disk	Space this dataset consumes on disk.
In Core	Space this dataset consumers in main memory.

The following icons are visible in the BUI view; some of these are only visible during hover-over of a dataset entry.
