public final class RecursiveDeleteClass used to store state required for running a recursive delete operation. Each recursive delete call should use a new instance of the class.
Static Fields
MAX_PENDING_OPS
public static final int MAX_PENDING_OPSThe query limit used for recursive deletes when fetching all descendants of the specified reference to delete. This is done to prevent the query stream from streaming documents faster than Firestore can delete.

MIN_PENDING_OPS
public static final int MIN_PENDING_OPSThe number of pending BulkWriter operations at which RecursiveDelete starts the next limit query to fetch descendants. By starting the query while there are pending operations, Firestore can improve BulkWriter throughput. This helps prevent BulkWriter from idling while Firestore fetches the next query.

REFERENCE_NAME_MIN_ID
public static final String REFERENCE_NAME_MIN_IDDatastore allowed numeric IDs where Firestore only allows strings. Numeric IDs are exposed to Firestore as idNUM, so this is the lowest possible negative numeric value expressed in that format.
This constant is used to specify startAt/endAt values when querying for all descendants in a single collection.
