public final class FeatureGroup
extends Object
implements SdkPojo, Serializable, ToCopyableBuilder<FeatureGroup.Builder,FeatureGroup>
```
Amazon SageMaker Feature Store stores features in a collection called Feature Group. A Feature Group can be visualized as a table which has rows, with a unique identifier for each row where each column in the table is a feature. In principle, a Feature Group is composed of features and values per features.

- Method Detail
  - featureGroupArn
```
public final String featureGroupArn()
```
    The Amazon Resource Name (ARN) of a FeatureGroup.
    
    Returns:
    
    The Amazon Resource Name (ARN) of a FeatureGroup.
  - featureGroupName
```
public final String featureGroupName()
```
    The name of the FeatureGroup.
    
    Returns:
    
    The name of the FeatureGroup.
  - recordIdentifierFeatureName
```
public final String recordIdentifierFeatureName()
```
    The name of the Feature whose value uniquely identifies a Record defined in the FeatureGroup FeatureDefinitions.
    
    Returns:
    
    The name of the Feature whose value uniquely identifies a Record defined in the FeatureGroup FeatureDefinitions.
  - eventTimeFeatureName
```
public final String eventTimeFeatureName()
```
    The name of the feature that stores the EventTime of a Record in a FeatureGroup.
    
    A EventTime is point in time when a new event occurs that corresponds to the creation or update of a Record in FeatureGroup. All Records in the FeatureGroup must have a corresponding EventTime.
    
    Returns:
    
    The name of the feature that stores the EventTime of a Record in a FeatureGroup .
    
    A EventTime is point in time when a new event occurs that corresponds to the creation or update of a Record in FeatureGroup. All Records in the FeatureGroup must have a corresponding EventTime.
  - hasFeatureDefinitions
```
public final boolean hasFeatureDefinitions()
```
    For responses, this returns true if the service returned a value for the FeatureDefinitions 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.
  - featureDefinitions
```
public final List<FeatureDefinition> featureDefinitions()
```
    A list of Features. Each Feature must include a FeatureName and a FeatureType.
    
    Valid FeatureTypes are Integral, Fractional and String.
    
    FeatureNames cannot be any of the following: is_deleted, write_time, api_invocation_time.
    
    You can create up to 2,500 FeatureDefinitions per FeatureGroup.
    
    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 hasFeatureDefinitions() method.
    
    Returns:
    
    A list of Features. Each Feature must include a FeatureName and a FeatureType.
    
    Valid FeatureTypes are Integral, Fractional and String.
    
    FeatureNames cannot be any of the following: is_deleted, write_time, api_invocation_time.
    
    You can create up to 2,500 FeatureDefinitions per FeatureGroup.
  - creationTime
```
public final Instant creationTime()
```
    The time a FeatureGroup was created.
    
    Returns:
    
    The time a FeatureGroup was created.
  - lastModifiedTime
```
public final Instant lastModifiedTime()
```
    A timestamp indicating the last time you updated the feature group.
    
    Returns:
    
    A timestamp indicating the last time you updated the feature group.
  - onlineStoreConfig
```
public final OnlineStoreConfig onlineStoreConfig()
```
    Returns the value of the OnlineStoreConfig property for this object.
    
    Returns:
    
    The value of the OnlineStoreConfig property for this object.
  - offlineStoreConfig
```
public final OfflineStoreConfig offlineStoreConfig()
```
    Returns the value of the OfflineStoreConfig property for this object.
    
    Returns:
    
    The value of the OfflineStoreConfig property for this object.
  - roleArn
```
public final String roleArn()
```
    The Amazon Resource Name (ARN) of the IAM execution role used to create the feature group.
    
    Returns:
    
    The Amazon Resource Name (ARN) of the IAM execution role used to create the feature group.
  - featureGroupStatus
```
public final FeatureGroupStatus featureGroupStatus()
```
    A FeatureGroup status.
    
    If the service returns an enum value that is not available in the current SDK version, featureGroupStatus will return FeatureGroupStatus.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from featureGroupStatusAsString().
    
    Returns:

    Returns:
    
    A free form description of a FeatureGroup.

```
public final boolean hasTags()
```
    For responses, this returns true if the service returned a value for the Tags 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.
