The cache and attributes settings for a hosted vector tile layer (item) can be used to set the cache and the attributes that are available for a vector tile service.
These settings allow you to:
- View the tile layers' current visible range.
- Enable tiles to be used in offline maps and applications.
- Rebuild the vector tile cache.
- Configure the attributes that are included in the cache.
What is a vector tile cache?
Vector tile services published to and hosted on ArcGIS portal support fast visualization of large datasets using a collection of pre-generated vector tiles. Vector tile layers are ideal when you need to view many features at once.
To take advantage of the drawing performance of hosted tiles, you can publish them from the hosted feature layers or hosted feature layer views you own. Tiles published from hosted features reflect the changes you make to the feature data.
How to manage tile cache properties
The steps to manage map tile cache settings are:
-
Sign into a data management tool with your ArcGIS account:
- Go to ArcGIS.com and sign in to your portal (ArcGIS Location Platform or ArcGIS Online)
- ArcGIS Enterprise portal (ArcGIS Enterprise)
- Find the item.
- Use the item page to manage cache settings.
Types of management operations
You can use an item page or the ArcGIS REST API to perform vector tile cache management operations. The most common operations include the following:
-
Service properties: Service properties contain the current settings of the vector tile service. These include a reference to the tile urls, the tiling schema, levels of detail and more.
-
Cache: The vector tile cache can be rebuilt. When edits occur in the source feature layer you need to rebuild the cache to include any changes from the source feature layer.
-
Feature attributes: Feature attributes can be included in the cache. Attributes included in the cache can be used in styling and for showing popups. Currently only supported in custom applications created using third-party software.
-
Offline mode: Allow the tiles to be downloaded and used in an offline map.
Code examples
You can use data management tools to manage tile cache of a vector tile service or you can use the ArcGIS REST APIs. The following examples illustrate how to programmatically get the properties, synchronize, set feature attributes, and set the offline mode of a vector tile service.
Get the service properties
To access all of the vector tile service properties directly, use the REST API VectorTileServer endpoint to perform a GET request and pass the json and token parameters. A JSON structure will be returned containing the current properties and values of the service.

}Synchronize the cache
The rebuild admin operation is used to start a job to rebuild the tile cache. A JSON response will be returned containing the status of the job request. If the request returns a status of success, you can use the job returned to track the status of the job.

}Set feature attributes
To manage the attributes that are included in the cache, use the REST API edit admin operation. Pass in a JSON object to the service parameter, with an array of strings representing the field names you want to include. Attributes in vector tiles can currently only be used in custom applications.
Request
POST https://{VectorTileServiceHost}/{organizationId}/arcgis/rest/admin/services/{ServiceName}/VectorTileServer/edit HTTP/1.1

}Response
{
"success": true
}Set offline mode
To enable a vector tile service for offline use, use the REST API edit admin operation with a POST request. The source parameter is the Item ID of the feature service that the vector tile service was created from. Set the export parameter to true to enable offline access or to false to disable offline access.
