    • status

      public final EnvironmentStatus status()

      The status of the Amazon MWAA environment.

      Valid values:

      • CREATING - Indicates the request to create the environment is in progress.

      • CREATING_SNAPSHOT - Indicates the request to update environment details, or upgrade the environment version, is in progress and Amazon MWAA is creating a storage volume snapshot of the Amazon RDS database cluster associated with the environment. A database snapshot is a backup created at a specific point in time. Amazon MWAA uses snapshots to recover environment metadata if the process to update or upgrade an environment fails.

      • CREATE_FAILED - Indicates the request to create the environment failed, and the environment could not be created.

      • AVAILABLE - Indicates the request was successful and the environment is ready to use.

      • PENDING - Indicates the request was successful, but the process to create the environment is paused until you create the required VPC endpoints in your VPC. After you create the VPC endpoints, the process resumes.

      • UPDATING - Indicates the request to update the environment is in progress.

      • ROLLING_BACK - Indicates the request to update environment details, or upgrade the environment version, failed and Amazon MWAA is restoring the environment using the latest storage volume snapshot.

      • DELETING - Indicates the request to delete the environment is in progress.

      • DELETED - Indicates the request to delete the environment is complete, and the environment has been deleted.

      • UNAVAILABLE - Indicates the request failed, but the environment did not return to its previous state and is not stable.

      • UPDATE_FAILED - Indicates the request to update the environment failed, and the environment was restored to its previous state successfully and is ready to use.

      • MAINTENANCE - Indicates that the environment is undergoing maintenance. Depending on the type of work Amazon MWAA is performing, your environment might become unavailable during this process. After all operations are done, your environment will return to its status prior to mainteneace operations.

      We recommend reviewing our troubleshooting guide for a list of common errors and their solutions. For more information, see Amazon MWAA troubleshooting.

      If the service returns an enum value that is not available in the current SDK version, status will return EnvironmentStatus.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from statusAsString().

    • hasAirflowConfigurationOptions

      public final boolean hasAirflowConfigurationOptions()
      For responses, this returns true if the service returned a value for the AirflowConfigurationOptions 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.

      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.

      The maximum number of web servers that you want to run in your environment. Amazon MWAA scales the number of Apache Airflow web servers up to the number you specify for MaxWebservers when you interact with your Apache Airflow environment using Apache Airflow REST API, or the Apache Airflow CLI. For example, in scenarios where your workload requires network calls to the Apache Airflow REST API with a high transaction-per-second (TPS) rate, Amazon MWAA will increase the number of web servers up to the number set in MaxWebserers. As TPS rates decrease Amazon MWAA disposes of the additional web servers, and scales down to the number set in MinxWebserers.

      Valid values: Accepts between 2 and 5. Defaults to 2.

    • toBuilder

      public Environment.Builder toBuilder()
      Description copied from interface: ToCopyableBuilder
      Take this object and create a builder that contains all of the current property values of this object.
      Specified by:
      toBuilder in interface ToCopyableBuilder<Environment.Builder,Environment>
      Returns:
      a builder for type T

    • builder

      public static Environment.Builder builder()

    • serializableBuilderClass

      public static Class<? extends Environment.Builder> serializableBuilderClass()

    • hashCode

      public final int hashCode()
      Overrides:
      hashCode in class Object

    • equals

      public final boolean equals(Object obj)
      Overrides:
      equals in class Object

    • equalsBySdkFields

      public final boolean equalsBySdkFields(Object obj)
      Description copied from interface: SdkPojo
      Indicates whether some other object is "equal to" this one by SDK fields. An SDK field is a modeled, non-inherited field in an SdkPojo class, and is generated based on a service model.

      If an SdkPojo class does not have any inherited fields, equalsBySdkFields and equals are essentially the same.

      Specified by:
      equalsBySdkFields in interface SdkPojo
      Parameters:
      obj - the object to be compared with
      Returns:
      true if the other object equals to this object by sdk fields, false otherwise.

    • toString

      public final String toString()
      Returns a string representation of this object. This is useful for testing and debugging. Sensitive data will be redacted from this string using a placeholder value.
      Overrides:
      toString in class Object

    • getValueForField

      public final <T> Optional<T> getValueForField(String fieldName, Class<T> clazz)

    • sdkFields

      public final List<SdkField<?>> sdkFields()
      Specified by:
      sdkFields in interface SdkPojo
      Returns:
      List of SdkField in this POJO. May be empty list but should never be null.
