Overview

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. 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.

#additional_configs ⇒ Hash<String,String>

Contains additional notebook engine ‘MAP<string, string>` parameter mappings in the form of key-value pairs. To specify an Athena notebook that the Jupyter server will download and serve, specify a value for the StartSessionRequest$NotebookVersion field, and then add a key named NotebookId to AdditionalConfigs that has the value of the Athena notebook ID.

Returns:

  • (Hash<String,String>)

#coordinator_dpu_size ⇒ Integer

The number of DPUs to use for the coordinator. A coordinator is a special executor that orchestrates processing work and manages other executors in a notebook session. The default is 1.

Returns:

  • (Integer)
