Response Structure

• (dict) --
  • SessionId (string) --

    The session ID.

  • Description (string) --

    The session description.

  • WorkGroup (string) --

    The workgroup to which the session belongs.

  • EngineVersion (string) --

    The engine version used by the session (for example, PySpark engine version 3 ). You can get a list of engine versions by calling ListEngineVersions.

  • EngineConfiguration (dict) --

    Contains engine configuration information like DPU usage.

    • CoordinatorDpuSize (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.

    • MaxConcurrentDpus (integer) --

      The maximum number of DPUs that can run concurrently.

    • DefaultExecutorDpuSize (integer) --

      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.

    • AdditionalConfigs (dict) --

      Contains additional notebook engine MAP<string, string> parameter mappings in the form of key-value pairs. To specify an Amazon S3 URI that the Jupyter server will download and serve, specify a value for the StartSessionRequest$NotebookVersion field, and then add a key named NotebookFileURI to AdditionalConfigs that has value of the Amazon S3 URI.

      • (string) --
        • (string) --
  • NotebookVersion (string) --

    The notebook version.

  • SessionConfiguration (dict) --

    Contains the workgroup configuration information used by the session.

    • ExecutionRole (string) --

      The ARN of the execution role used for the session.

    • WorkingDirectory (string) --

      The Amazon S3 location that stores information for the notebook.

    • IdleTimeoutSeconds (integer) --

      The idle timeout in seconds for the session.

    • EncryptionConfiguration (dict) --

      If query results are encrypted in Amazon S3, indicates the encryption option used (for example, SSE_KMS or CSE_KMS ) and key information.

      • EncryptionOption (string) --

        Indicates whether Amazon S3 server-side encryption with Amazon S3-managed keys ( SSE_S3 ), server-side encryption with KMS-managed keys ( SSE_KMS ), or client-side encryption with KMS-managed keys ( CSE_KMS ) is used.

        If a query runs in a workgroup and the workgroup overrides client-side settings, then the workgroup's setting for encryption is used. It specifies whether query results must be encrypted, for all queries that run in this workgroup.

      • KmsKey (string) --

        For SSE_KMS and CSE_KMS , this is the KMS key ARN or ID.

  • Status (dict) --

    Contains information about the status of the session.

    • StartDateTime (datetime) --

      The date and time that the session started.

    • LastModifiedDateTime (datetime) --

      The most recent date and time that the session was modified.

    • EndDateTime (datetime) --

      The date and time that the session ended.

    • IdleSinceDateTime (datetime) --

      The date and time starting at which the session became idle. Can be empty if the session is not currently idle.

    • State (string) --

      The state of the session. A description of each state follows.

      CREATING - The session is being started, including acquiring resources.

      CREATED - The session has been started.

      IDLE - The session is able to accept a calculation.

      BUSY - The session is processing another task and is unable to accept a calculation.

      TERMINATING - The session is in the process of shutting down.

      TERMINATED - The session and its resources are no longer running.

      DEGRADED - The session has no healthy coordinators.

      FAILED - Due to a failure, the session and its resources are no longer running.

    • StateChangeReason (string) --

      The reason for the session state change (for example, canceled because the session was terminated).

  • Statistics (dict) --

    Contains the DPU execution time.

    • DpuExecutionInMillis (integer) --

      The data processing unit execution time for a session in milliseconds.
