DynamicEntityDataSourcePurgeOptions

class DynamicEntityDataSourcePurgeOptions

Purge options for a dynamic entity data source. Data received from a DynamicEntityDataSource is cached in memory on the client and can grow quickly depending on the number of dynamic entities and frequency of updates. Use this class and the DynamicEntityDataSource.purgeOptions property to control app storage in the local data cache.

Properties on this object affect cached observations and should not be confused with similar options in TrackDisplayProperties which are applied on the DynamicEntityLayer and affect visibility of observations on a map or scene.

By default, the maximum total number of observations stored is 100,000 with no limit to the number of observations per track and no observation age limit.
