description

string

A human-readable name of the task.
selectors[]

string

An explicit list of columns to include in the result.
requestId

string

A unique string used to detect duplicated requests. If more than one request is made by the same user with the same non-empty requestId, only one of those requests may successfully start a long-running operation. requestId may contain the characters a..z, A..Z, 0-9, or '-'. requestId may be at most 60 characters long.
maxErrorMeters

number

The max allowed error in meters when transforming geometry between coordinate systems. If empty, the max error is 1 meter by default.
maxVertices

integer

Max number of uncut vertices per geometry; geometries with more vertices will be cut into pieces smaller than this size.
workloadTag

string

User supplied label to track this computation.
priority

integer

Optional. The priority of the export task within the project. Higher priority tasks are scheduled sooner. Must be an integer between 0 and 9999. Defaults to 100 if not set.
Union field export_options. Options describing where and how to store the results. export_options can be only one of the following:
fileExportOptions

object (TableFileExportOptions)

If specified, configures export as a file.
assetExportOptions

object (TableAssetExportOptions)

If specified, configures export as an Earth Engine asset.
featureViewExportOptions

object (FeatureViewAssetExportOptions)

If specified, configures export as a FeatureView map.
bigqueryExportOptions

object (BigQueryExportOptions)

If specified, configures export of tabular data to BigQuery.
