Feature Service

Description

A feature service can contain datasets (for example, tables and views) with or without a spatial column. Datasets with a spatial column are considered layers; those without a spatial column are considered tables. A feature service allows clients to query and edit feature geometry and attributes.

This resource provides basic information about the feature service, including the feature layers and tables that it contains, the service description, and so on.

The capabilities property returns Create, Delete, Extract, Query, Update, Sync, and Uploads capabilities. The Uploads capability is included if Create, Delete, or Update is enabled for a feature service. The Editing capability is included if Create, Delete, and Update is enabled and allowGeometryUpdates is true. The Sync capability allows editors to make local edits and periodically sync with the feature service. The Extract capability allows editors to create a local copy of data without the ability to sync with the feature service.

The maxRecordCount property returns the maximum number of records that will be returned at once for a query. The Feature Service resource has an input parameters option and outSR to support viewing of a feature service footprint.

The following properties describe features that have been added to Feature Service through the releases. If the property does not exist, it's equivalent to having a value of false or is not set:

• hasVersionedData will be true if the data is versioned.
• supportedQueryFormats returns the formats in which query results can be returned.
• allowGeometryUpdates returns true if the geometry of the features in the layer can be edited.
• zDefault and enableZDefaults are returned for a service configured with default z-values.
• supportsDisconnectedEditing will be true to indicate the support for disconnected editing.
• syncEnabled will be true to indicate the support for sync.
• supportsRegisterExistingData will be true if the service supports registration of existing data for createReplica . Only present if syncEnabled is true .
• supportsSyncDirectionControl will be true if the service will allow control of data sync direction. Only present if syncEnabled is true .
• supportsPerLayerSync will be true if the layers can be synchronized independently, and the service will accept a value of perLayer for the sync model during the createReplica operation. If supportsPerLayerSync is false , the only sync model supported is perReplica . Only present if syncEnabled is true .
• supportsPerReplicaSync will be true if the layers can be synchronized together, and the service will accept a value of perReplica for the sync model during the createReplica operation. If supportsPerReplicaSync is false , the only sync model supported is perLayer . Only present if syncEnabled is true .
• supportsSyncModelNone will be true if the service supports extracting data without the creation of a replica. If true , the service will accept setting syncModel=none for the sync model during the createReplica operation.
• supportsAttachmentsSyncDirection will be true if the service supports options to define how attachments will be synced. If true , the service will accept setting the attachmentsSyncDirection parameter during the createReplica operation.
• supportsRollbackOnFailure will be true if the rollbackOnFailure parameter can be set to true or false when running the synchronizeReplica operation. supportsRollbackOnFailure will be false if the synchronizeReplica operation does not support the parameter.
• supportsAsync will be true if the service can execute sync operations asynchronously. Only present if syncEnabled is true .
• supportsApplyEditsWithGlobalIds in the root resource will be true if all layers in the service have supportsApplyEditsWithGlobalIds as true . See Feature Service Layer Properties for more details.
• A feature service that supports the append API exposes the supportsAppend metadata property. When the supportsAppend property is absent or is false , the owner of the feature service cannot use the append API. Also the Append capability cannot be added to a feature service if the supportsAppend is true . See Append (Feature Service) or Append (Feature Service/Layer) for more details.
• Introduced with the April 2021 ArcGIS Online release, the supportedExportFormats property, when present, describes the formats supported when exporting content from a feature layer item in a portal. The associated feature layer item can be found using the feature service serviceItemId property. The export operation is called through the Portal Directory (Sharing API) and is not a feature service operation, thus this property only applies to services that are federated with a portal.

New at 11.3

• The esriFieldTypeTimeOnly, esriFieldTypeDateOnly, esriFieldTypeTimestampOffset, and esriFieldTypeBigInteger field types have exited beta and are now supported.

• Feature services can now be published from a Snowflake data source with Geography type using ArcGIS Pro 3.3 or later.

• Feature services now support one-way feature service-to-feature service synchronization.

• Support has been added for sync on services with 64 bit objectID fields and Utility Network data. The sync capability is not supported on services without Utility Network layers when 64 bit objectID fields are present.

• Service webhooks are now supported with branch versioned data. See the Create webhooks documentation for more details.

New at 11.2

General updates

The updates below have been added, in general, for hosted feature services and non-hosted feature services (referencing enterprise geodatabases) publish from ArcGIS Pro:

• Oriented imagery data can now be published as feature service layers. These layers will be of the type Oriented Imagery Layers and will list information specific to oriented imagery under the orientedImageryInfo layer-level property. See the Oriented Imagery topic for more information.

• Feature services now support WKT2. Service-level operations that allow for spatial reference information as input for specific parameters will now accept a WKT2 value and generate an appropriate response. For more information on WKT2 examples, reference the following JSON example. For WKT2 values, see the Using spatial references documentation.

• Four new field types have been added as beta features: esriFieldTypeTimeOnly , esriFieldTypeDateOnly , esriFieldTypeTimestampOffset and esriFieldTypeBigInteger . The beta only applies to feature services that include these fields. The sync capability is not supported when these fields are present. The esriFieldTypeTimeOnly , esriFieldTypeDateOnly and esriFieldTypeTimestampOffset fields return ISO8601 values and require values in ISO8601 when applying edits.

• Support has been added for esriFieldTypeDate fields that contain high precision values. These fields can contain up to millisecond precision, although some clients may not use the full precision for querying or editing. Both hosted feature services and non-hosted feature services referencing geodatabase datasets that include high precision date fields support these new field types. Support is indicated when a esriFieldTypeDate field has a precision property set as 1.

Hosted feature services

Feature services on relational data store in ArcGIS Enterprise now support contingent attribute values. Support for this is indicated when the service-level supportsQueryContingentValues property is set as true .

Cloud Data Warehouse (CDW) feature services

Starting at ArcGIS Enterprise 11.2, feature services can now be published from an Amazon Redshift data source using ArcGIS Pro 3.2 or later.

New at 11.1

General updates

The updates below have been added, in general, for hosted feature services and non-hosted feature services (referencing enterprise geodatabases) publish from ArcGIS Pro:

• Starting at ArcGIS Enterprise 11.1, feature services can now be published from a Snowflake data source using ArcGIS Pro 3.1 or later.
• The service- and layer-level supportedExportFormats properties have been expanded to include csv and geojson as supported formats for exported data.
• Starting at ArcGIS Enterprise 11.1, the Create Replica operation will not require the geometry parameter when its syncModel parameter is set as none . This will cause all records to be included for the feature layer unless other filters are set. However, the geometry parameter is required if syncModel values other than none are used.
• Both the service- and layer-level applyEdits operations now include the editsUploadId parameter. This parameter references an upload ID from an uploaded file containing service edits, providing the option to pre-upload edits to the ArcGIS Server and reference them rather than provide edits in-line with the edits parameter. Support for the new parameter is indicated when the service- and layer-level supportsApplyEditsbyUploadID properties, under advancedEditingCapabilities , are set to true .

Enterprise geodatabase

The update below has been added for non-hosted feature services that reference enterprise geodatabase data and are published from ArcGIS Pro:

• Starting at ArcGIS Enterprise 11.1, the Extract Changes operation includes support for the returnDeletedFeatures parameter. This parameter allows you to specify whether the full information for a deleted feature is returned, or just the feature's identifier.

Hosted feature services

The updates below have been added for hosted feature services from a relational data store:

• Both the service- and layer-levelappend operations feature the following enhancements:

• The Append capability can now be set for qualifying hosted feature services to allow non-service owners and non-organization administrators with access to the feature service to run the append operations. In prior releases, the Append capability could not be set for hosted feature services, limiting the scope of those who could use the append operations on a given hosted feature service.

• The esriFieldTypeBlob field type is now supported.

• The Relationships resource is now supported for qualifying hosted feature services. Support for this is indicated when the service-level supportsRelationshipsResource property is true .

New at 11.0

General updates

The updates below have been added, in general, for hosted feature services and non-hosted feature services (referencing enterprise geodatabases) published from ArcGIS Pro.

• The feature service resource for hosted and non-hosted feature services published for ArcGIS Indoors include an isIndoorsService property, set as true , on their service resource. Editable feature services with the isIndoorsService property as true can be edited by viewer users if the organization has a valid Indoors license.
• At this release, feature services can be published from a Google BigQuery data source using ArcGIS Pro 3.0 or later.
• The service-level supportedExportFormats property has been expanded to include shapefile as a supported value.
• At this release, a file geodatabase extracted from a feature service using the createReplica operation now includes a GDB_ServiceItems table. This table contains the feature service and feature service layer resource JSON information of the service the table was extracted from. For more information, see the Create Replica topic.

Non-hosted feature services

The following updates apply to non-hosted feature services (referencing enterprise geodatabase data) published from ArcGIS Pro.

• The createReplica operation's replicaOptions parameter has expanded its SyncDataOptions accepted property values, as indicated by the feature service's supportedSyncDataOptions service-level property. For more information, see the Create Replica topic.

• The synchronizeReplica operation includes a new parameter, reconcileBranchVersion , that can be applied to replicas created from branch versioned data where the feature service has the versionPerDownloadedMap setting. For more information on the new parameter, see the Synchronize Replica topic.

• The extractChanges operation has been expanded to support the following changes, support for which depend on properties under extractChangesCapabilities on the service-level resource:

  • A new parameter, fieldsToCompare . Support for this is indicated when the supportsFieldsToCompare property, under extractChangesCapabilities , is set as true .
  • The ability to return features rather than IDs only. Support for this is indicated when the supportsFeatureReturn property, under extractChangesCapabilities , is set as true .
  • A new parameter, serverGens . Support for this is indicated when the supportsServerGens property, under extractChangesCapabilities , is set as true .
  • The ability to return attachment differences. Support for this is indicated when the supportsReturnAttachments property, under extractChangesCapabilities , is set as true

  For more information on these changes, see the Extract Changes topic.

Hosted feature services

The following changes apply for hosted feature services:

• The service-level applyEdits operation now supports an async parameter. Support for this parameter is indicated when the service-level supportsAsyncApplyEdits property, under advancedEditingCapabilities , is true . For more information on this new parameter, see the Apply Edits topic.
• The service-level applyEdits operation includes a new parameter, returnEditResults . Support for this new parameter is indicated by a feature service having the service-level supportsReturnEditResults property, under advancedEditingCapabilities , set as true . To learn more about the new parameter, see the service-level Apply Edits topic.

The following updates apply to hosted feature services running on a relational data store:

• The ChangeTracking capability can now be enabled on a feature service resource using the updateDefinition operation. Adding ChangeTracking exposes the extractChanges options and adds the extractChangesCapabilities property to the feature service resource. This property describes the extractChanges operation that are supported for that feature service.

New at 10.9.1

• The feature service resource includes a supportedExportFormats property that describes the formats supported when exporting data. Data can be exported when the extract or sync capability is enabled and the createReplica operation is called with the syncModel=none option.
• The service level applyEdits operation for hosted feature services in ArcGIS Online, and nonhosted feature services in ArcGIS Enterprise, includes an option to process requests asynchronously. This option is ideal for longer running edit operations that may otherwise time out. The async parameter can be used if the service resource has the supportsAsyncApplyEdits property as true under advancedEditingCapabilities .

New at 10.9

• The feature service resource's syncCapabilities object now supports a supportsBiDirectionalSyncForServer property. Hosted feature services, feature services running on branch versioned data or feature services running on nonversioned with archiving data can support bidirectional syncing. Currently bidirectional sync workflows require the target to be a hosted feature service running on either ArcGIS Online or ArcGIS Enterprise 10.9. Bidirectional syncing with another service requires replica tracking to be enabled on the data. For hosted feature services, replica tracking is automatically enabled when sync is enabled, starting at 10.9. For more information, see Share content with collaboration groups, createReplica , and synchronizeReplica .
• The extractChanges operation includes a new parameter that, when true , returns whether geometry updates have been made to a layer in the feature service. The new parameter is supported when the service's extractChangesCapabilities property includes supportsReturnHasGeometryUpdates as true .
• The createReplica operation's syncDataOptions parameter has been expanded to add full annotation and an option to include a subset of Utility Network system information when taking data offline. The services supportedSyncDataOptions property indicates which of the syncDataOptions are available for a service. See the createReplica operation for more information on these values.

New at 10.8.1

• Feature services now support topology layers. Topology layers are composite layers that reference subLayers and do not have any capabilities . The subLayer references describe the layer's error features and dirty areas. In clients such as ArcGIS Pro 2.6, topology layers are used in conjunction with the validation service to support topology validation and error feature correction.
• When a topology layer is included, the controllerDatasetLayers array property adds a reference to it in the topologyLayerIds property. To see an example of topology layers being included in a feature service, see the topology example in the Example Usage section below.
• New advancedReplicaResourcesCapabilities properties in the syncCapabilities object are provided for sync-enabled feature services published from ArcGIS Pro that reference enterprise geodatabase data. These describe new parameters that can be passed to the replicas resource. See Replicas for more details.
• Hosted and nonhosted feature services running on a federated server include a serviceItemId property at 10.8.1. This describes the ID of the associated feature layer item in the home app. Hosted feature services in ArcGIS Enterprise have supported this property since 10.7.
• If the connected user has the Version Management privilege assigned to them through either being assigned the default administrator or a custom role, they can perform additional operations on branch versioned data (isDataBranchVersioned as true ). This includes editing protected and private branch versions owned by others, as long as the service allows editing. This also includes being able to access and unregister replicas owned by others for services based on branch versioned data. A user with the Version Management privilege can sync to a protected default version on editable services based on branch versioned data.

New at 10.8

• The feature service resource now returns the supportsDatumTransformation property. This property is returned as true if the service supports the addition of datum transformations. If true , Create Replica, the layer-level Query, Query Related, and service and layer-level Apply Edits operations will allow datum transformations.
• The appropriate user type extension is required when editing feature services that contain Utility Network or Parcel Fabric layers. The user type extensions are not required to query Utility Network or Parcel Fabric layers through the feature service. The userTypeExtensions property of the Layer resource indicates whether the layer is part of a parcelFabric or utilityNetwork .
• The supportsReturnServiceEditsInSourceSR property in advancedEditingCapabilities indicates whether the option to supportsReturnServiceEditsInSourceSR is available on the service's Apply Edits operation.
• The datumTransformations property indicates the default datum transformations applied with operations on the service.
• The referenceScale property represents the scale at which a participating layer's symbol size and text are fixed.
