Interface CfnWorkGroupPropsMixin.IEngineConfigurationProperty

The engine configuration for the workgroup, which includes the minimum/maximum number of Data Processing Units (DPU) that queries should use when running in provisioned capacity.

Namespace: Amazon.CDK.Mixins.Preview.AWS.Athena.Mixins

Assembly: Amazon.CDK.Mixins.Preview.dll

Syntax (csharp)

public interface CfnWorkGroupPropsMixin.IEngineConfigurationProperty

Syntax (vb)

Public Interface CfnWorkGroupPropsMixin.IEngineConfigurationProperty

Remarks

If not specified, Athena uses default values (Default value for min is 4 and for max is Minimum of 124 and allocated DPUs).

To specify DPU values for PC queries the WG containing EngineConfiguration should have the following values: The name of the Classifications should be athena-query-engine-properties , with the only allowed properties as max-dpu-count and min-dpu-count .
