Loading methods [Beta]

By default, the Map application loads all objects in a layer to render them on the map. This inherently creates a scale limitation, as you can only render as much data as you can load from the Ontology into your browser. The Loading method configuration facilitates the presentation of high-scale object sets by restricting the application to load only the necessary data required to display the visible extent of the map.

Configure loading methods

If loading method configuration is available on your enrollment, you can configure it in a geometry with the Loading method dropdown menu in the style panel.

The loading method options are as follows:

• Auto: By default, the application will use the contents of the layer to infer the optimal choice between tile-based and object-based loading.
• Tile: Loads simplified geometry data within the bounds of the map viewport. This option is best suited for large object sets and prioritizing performance.
• Object: Loads full details for individual objects. This option is best suited for complex styling settings.

You will only be able to select a loading method selection for a geometry if the following is true:

• The object type for the layer has at least one geohash or geoshape property.
• Tile-based rendering is supported for the geometry type. Only icon, circle, and geoshape-based geometries are currently supported.
• Tile-based rendering is enabled for the object type. Contact Palantir Support to verify whether your environment has additional requirements for a specific object type.

Add objects with tile-based loading methods

For object types that support tile-based loading methods, the search dialog will not limit how many objects can be added to the map. As such, the Add all option will always be enabled.

Tile-based loading method compatibility

Objects rendered in a tile-backed geometry do not interoperate correctly with a number of other Map application features for the following reasons:

• As a feature in the beta phase of development, many tile-based loading method capabilities are actively being developed and will be available when the feature reaches general availability.
• Many of the features that are incompatible with tile-based geometries require loading data from services that cannot support the scale of data rendered in tile-based layers.

The following sections list the Map capabilities that are not compatible with tile-based loading methods.

Styling

Geohash and geoshape properties are the only geometry sources supported for object layer geometries, and only property values are supported for all value-based styling options.

As such, the following options are not supported:

• Time series-based styling (measures and TSPs)
• Derived property functions
• Opacity by time
• Labels
• Timeline stylers

Filtering

Objects displayed in a tile-based geometry do not respect filtering applied in the histogram or the timeline.

Shapes

Objects displayed in a tile-based geometry will not be included when creating shapes from the active selection.
