IGQIOptimizableDataSource interface

Available from DataMiner 10.3.3/10.4.0 onwards.

Note

This interface is only used by the GQI framework in the life cycle for ad hoc data sources from DataMiner 10.5.0 [CU2]/10.5.5 onwards when using the GQI DxM.

Definition

• Namespace: Skyline.DataMiner.Analytics.GenericInterface
• Assembly: SLAnalyticsTypes.dll

The IGQIOptimizableDataSource interface can be used to optimize an ad hoc data source based on operators added to a query.

Tip

You can implement this interface to forward sort operations to an underlying database to improve performance.

Methods

IGQIQueryNode Optimize(IGQIDataSourceNode currentNode, IGQICoreOperator nextOperator)

Called when an optimizable operator is appended directly to the ad hoc data source. Given the current query node that represents the ad hoc data source and the next operator, it should return the resulting query node.

Tip

Learn more about when this method is called within an ad hoc data source.

Important

• The Optimize method may not be called if there are no supported subsequent operators.
• The Optimize method will be called each time the next operator changes.

Note

Currently, the Optimize method only triggers for filter operators (IGQIFilterOperator) and (from DataMiner 10.4.0/10.4.1 onwards) sort operators (IGQISortOperator).

Parameters

• IGQIDataSourceNode currentNode: A reference to the current node.

• IGQICoreOperator nextOperator: A reference to the next operator.
