- Method Detail
  - coordinatorDpuSize
```
public final Integer coordinatorDpuSize()
```
    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:
    
    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.
  - maxConcurrentDpus
```
public final Integer maxConcurrentDpus()
```
    The maximum number of DPUs that can run concurrently.
    
    Returns:
    
    The maximum number of DPUs that can run concurrently.
  - defaultExecutorDpuSize
```
public final Integer defaultExecutorDpuSize()
```
    The default number of DPUs to use for executors. An executor is the smallest unit of compute that a notebook session can request from Athena. The default is 1.
    
    Returns:
    
    The default number of DPUs to use for executors. An executor is the smallest unit of compute that a notebook session can request from Athena. The default is 1.
  - hasAdditionalConfigs
```
public final boolean hasAdditionalConfigs()
```
    For responses, this returns true if the service returned a value for the AdditionalConfigs property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.
  - additionalConfigs
```
public final Map<String,String> additionalConfigs()
```
    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.
    
    Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.
    
    This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasAdditionalConfigs() method.

  - hasSparkProperties
```
public final boolean hasSparkProperties()
```
    For responses, this returns true if the service returned a value for the SparkProperties property.

  - sparkProperties
```
public final Map<String,String> sparkProperties()
```
    Specifies custom jar files and Spark properties for use cases like cluster encryption, table formats, and general Spark tuning.
