Resource: MigrationSubtask

A subtask for a migration which carries details about the configuration of the subtask. The content of the details should not matter to the end user, but is a contract between the subtask creator and subtask worker.

Fields
name

string

Output only. Immutable. The resource name for the migration subtask. The ID is server-generated.

Example: projects/123/locations/us/workflows/345/subtasks/678
taskId

string

The unique ID of the task to which this subtask belongs.
type

string

The type of the Subtask. The migration service does not check whether this is a known type. It is up to the task creator (i.e. orchestrator or worker) to ensure it only creates subtasks for which there are compatible workers polling for Subtasks.
state

enum (State)

Output only. The current state of the subtask.
processingError

object (ErrorInfo)

Output only. An explanation that may be populated when the task is in FAILED state.
resourceErrorDetails[]

object (ResourceErrorDetail)

Output only. Provides details to errors and issues encountered while processing the subtask. Presence of error details does not mean that the subtask failed.
resourceErrorCount

integer

The number or resources with errors. Note: This is not the total number of errors as each resource can have more than one error. This is used to indicate truncation by having a resourceErrorCount that is higher than the size of resourceErrorDetails.
createTime

string (Timestamp format)

Time when the subtask was created.
lastUpdateTime

string (Timestamp format)

Time when the subtask was last updated.
metrics[]

object (TimeSeries)

The metrics for the subtask.

RUNNING The subtask is running, i.e. it is assigned to a worker for execution.
SUCCEEDED The subtask finished successfully.
FAILED The subtask finished unsuccessfully.
