Each RPC normalizes the partition IDs of the keys in its input entities, and always returns entities with keys with normalized partition IDs. This applies to all keys and entities, including those in values, except keys with both an empty path and an empty or unset partition ID. Normalization of input keys sets the project ID (if not already set) to the project ID from the request.

v1

constructor(opts?: ClientOptions);

Construct an instance of DatastoreClient.

static get apiEndpoint(): string;

The DNS address for this API service - same as servicePath(), exists for compatibility reasons.

datastoreStub?: Promise<{
        [name: string]: Function;
    }>;

descriptors: Descriptors;

innerApiCalls: {
        [name: string]: Function;
    };

static get port(): number;

The port for this API service.

static get scopes(): string[];

The scopes needed to make gRPC calls for every method defined in this service.

static get servicePath(): string;

The DNS address for this API service.

Terminate the gRPC channel and close the client.

The client will no longer be usable and all future behavior is undefined.

{Promise} A promise that resolves when the client is closed.

commit(request?: protos.google.datastore.v1.ICommitRequest, options?: CallOptions): Promise<[protos.google.datastore.v1.ICommitResponse, protos.google.datastore.v1.ICommitRequest | undefined, {} | undefined]>;

getProjectId(): Promise<string>;

getProjectId(callback: Callback<string, undefined, undefined>): void;

initialize(): Promise<{
        [name: string]: Function;
    }>;

Initialize the client. Performs asynchronous operations (such as authentication) and prepares the client. This function will be called automatically when any class method is called for the first time, but if you need to initialize it before calling an actual method, feel free to call initialize() directly.

You can await on this method if you want to make sure the client is initialized.

{Promise} A promise that resolves to an authenticated service stub.
