`Protected`_getBulkAttributes

_getBulkAttributes(bulk, _extent?): Promise<(undefined | Record<string, unknown>)[]>
Protected
Optional bulk attribute retrieval for multiple keys. Can be implemented for optimal loading of data. Provides a webmercator extent to limit the lookup if needed. You MUST return a same length array as keys, with undefined for missing attributes.
Parameters
- bulk: {
  feature: EventFeature;
  key: string;
  }[]
  array of key and feature pairs to retrieve attributes for
- Optional_extent: Extent
  optional extent in webmercator to limit attribute lookup on certain providers.
Returns Promise<(undefined | Record<string, unknown>)[]>
