// The Cloud Firestore Admin API.
//
// This API provides several administrative services for Cloud Firestore.
//
// Project, Database, Namespace, Collection, Collection Group, and Document are
// used as defined in the Google Cloud Firestore API.
//
// Operation: An Operation represents work being performed in the background.
//
// The index service manages Cloud Firestore indexes.
//
// Index creation is performed asynchronously.
// An Operation resource is created for each such asynchronous operation.
// The state of the operation (including any errors encountered)
// may be queried via the Operation resource.
//
// The Operations collection provides a record of actions performed for the
// specified Project (including any Operations in progress). Operations are not
// created directly but through calls on other collections or resources.
//
// An Operation that is done may be deleted so that it is no longer listed as
// part of the Operation collection. Operations are garbage collected after
// 30 days. By default, ListOperations will only return in progress and failed
// operations. To list completed operation, issue a ListOperations request with
// the filter `done: true`.
//
// Operations are created by service `FirestoreAdmin`, but are accessed via
// service `google.longrunning.Operations`.
