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.
