}
Fields
name

string

The pipeline name. For example: projects/PROJECT_ID/locations/LOCATION_ID/pipelines/PIPELINE_ID.

  • PROJECT_ID can contain letters ([A-Za-z]), numbers ([0-9]), hyphens (-), colons (:), and periods (.). For more information, see Identifying projects.
  • LOCATION_ID is the canonical ID for the pipeline's location. The list of available locations can be obtained by calling google.cloud.location.Locations.ListLocations. Note that the Data Pipelines service is not available in all regions. It depends on Cloud Scheduler, an App Engine application, so it's only available in App Engine regions.
  • PIPELINE_ID is the ID of the pipeline. Must be unique for the selected project and location.
displayName

string

Required. The display name of the pipeline. It can contain only letters ([A-Za-z]), numbers ([0-9]), hyphens (-), and underscores (_).
type

enum (PipelineType)

Required. The type of the pipeline. This field affects the scheduling of the pipeline and the type of metrics to show for the pipeline.
state

enum (State)

Required. The state of the pipeline. When the pipeline is created, the state is set to 'PIPELINE_STATE_ACTIVE' by default. State changes can be requested by setting the state to stopping, paused, or resuming. State cannot be changed through pipelines.patch requests.
createTime

string (Timestamp format)

Output only. Immutable. The timestamp when the pipeline was initially created. Set by the Data Pipelines service.

A timestamp in RFC3339 UTC "Zulu" format, with nanosecond resolution and up to nine fractional digits. Examples: "2014-10-02T15:01:23Z" and "2014-10-02T15:01:23.045123456Z".
lastUpdateTime

string (Timestamp format)

Output only. Immutable. The timestamp when the pipeline was last modified. Set by the Data Pipelines service.

A timestamp in RFC3339 UTC "Zulu" format, with nanosecond resolution and up to nine fractional digits. Examples: "2014-10-02T15:01:23Z" and "2014-10-02T15:01:23.045123456Z".
workload

object (Workload)

Workload information for creating new jobs.
scheduleInfo

object (ScheduleSpec)

Internal scheduling information for a pipeline. If this information is provided, periodic jobs will be created per the schedule. If not, users are responsible for creating jobs externally.
jobCount

integer

Output only. Number of jobs.
schedulerServiceAccountEmail

string

Optional. A service account email to be used with the Cloud Scheduler job. If not specified, the default compute engine service account will be used.
pipelineSources

map (key: string, value: string)

Immutable. The sources of the pipeline (for example, Dataplex). The keys and values are set by the corresponding sources during pipeline creation.

An object containing a list of "key": value pairs. Example: { "name": "wrench", "mass": "1.3kg", "count": "3" }.

PipelineType

The type of a pipeline. For example, batch or streaming.

Enums
PIPELINE_TYPE_UNSPECIFIED The pipeline type isn't specified.
PIPELINE_TYPE_BATCH A batch pipeline. It runs jobs on a specific schedule, and each job will automatically terminate once execution is finished.
PIPELINE_TYPE_STREAMING A streaming pipeline. The underlying job is continuously running until it is manually terminated by the user. This type of pipeline doesn't have a schedule to run on, and the linked job gets created when the pipeline is created.

State

The current state of pipeline execution.

Enums
STATE_UNSPECIFIED The pipeline state isn't specified.
STATE_RESUMING The pipeline is getting started or resumed. When finished, the pipeline state will be 'PIPELINE_STATE_ACTIVE'.
STATE_ACTIVE The pipeline is actively running.
STATE_STOPPING The pipeline is in the process of stopping. When finished, the pipeline state will be 'PIPELINE_STATE_ARCHIVED'.
STATE_ARCHIVED The pipeline has been stopped. This is a terminal state and cannot be undone.
STATE_PAUSED The pipeline is paused. This is a non-terminal state. When the pipeline is paused, it will hold processing jobs, but can be resumed later. For a batch pipeline, this means pausing the scheduler job. For a streaming pipeline, creating a job snapshot to resume from will give the same effect.

Workload

Workload details for creating the pipeline jobs.
