Type of operation: Metadata

Usage

interface interfaceName, fieldBinding ...

Argument	Type	Required	Multiple
interfaceName	string	Required	Only one
fieldBinding	expression	Required	Can be multiple

Accelerable

interface is always accelerable if the input is accelerable. A dataset that only uses accelerable verbs, can be accelerated, making queries on the dataset respond faster.

Examples

interface "notification", kind:myKindStr, description:logText, importance:sevInt

Make this dataset implement the ‘notification’ interface, binding the existing column ‘myKindStr’ to the ‘kind’ interfaceName, the existing column ‘logText’ to the ‘description’ interfaceName, and the existing column ‘sevInt’ to the ‘importance’ interfaceName.

interface "metric", metric:metricNameColumn, value:metricValueColumn

Make this dataset implement the ‘metric’ interface. Bind the existing column containing metric names (‘metricNameColumn’) to the ‘metric’ interfaceName, and the existing column containing ‘float64’ metric values (‘metricValueColumn’) to the ‘value’ interfaceName.
