+// The Cloud Firestore Admin API.
+//
+// This API provides several administrative services for Cloud Firestore.
+//
+// # Concepts
+//
+// Project, Database, Namespace, Collection, and Document are used as defined in
+// the Google Cloud Firestore API.
+//
+// Operation: An Operation represents work being performed in the background.
+//
+//
+// # Services
+//
+// ## Index
+//
+// 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.
+//
+// ## Metadata
+//
+// Provides metadata and statistical information about data in Cloud Firestore.
+// The data provided as part of this API may be stale.
+//
+// ## Operation
+//
+// 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 not yet done may be cancelled. The request to cancel is
+// asynchronous and the Operation may continue to run for some time after the
+// request to cancel is made.
+//
+// An Operation that is done may be deleted so that it is no longer listed as
+// part of the Operation collection.
+//
+// Operations are created by service `FirestoreAdmin`, but are accessed via
+// service `google.longrunning.Operations`.
+service FirestoreAdmin {
+  // Creates the specified index.
+  // A newly created index's initial state is `CREATING`. On completion of the
+  // returned [google.longrunning.Operation][google.longrunning.Operation], the state will be `READY`.
+  // If the index already exists, the call will return an `ALREADY_EXISTS`
+  // status.
+  //
+  // During creation, the process could result in an error, in which case the
+  // index will move to the `ERROR` state. The process can be recovered by
+  // fixing the data that caused the error, removing the index with
+  // [delete][google.firestore.admin.v1beta1.FirestoreAdmin.DeleteIndex], then re-creating the index with

+// *    `read_time` - The time at which a particular state was observed. Used
+//      to denote a consistent snapshot of the database or the time at which a
+//      Document was observed to not exist.
+// *    `commit_time` - The time at which the writes in a transaction were
