The Cloud Firestore service.

Cloud Firestore is a fast, fully managed, serverless, cloud-native NoSQL document database that simplifies storing, syncing, and querying data for your mobile, web, and IoT apps at global scale. Its client libraries provide live synchronization and offline support, while its security features and integrations with Firebase and Google Cloud Platform (GCP) accelerate building truly serverless apps.

The underlying gRPC Firestore client

Property Value
Type	Description

Methods

BatchGetDocuments(BatchGetDocumentsRequest, CallSettings)

public virtual FirestoreClient.BatchGetDocumentsStream BatchGetDocuments(BatchGetDocumentsRequest request, CallSettings callSettings = null)

Gets multiple documents.

Documents returned by this method are not guaranteed to be returned in the same order that they were requested.

Parameters
Name	Description
request	BatchGetDocumentsRequest The request object containing all of the parameters for the API call.
callSettings	CallSettings If not null, applies overrides to this RPC call.

Returns
Type	Description
FirestoreClient.BatchGetDocumentsStream	The server stream.

Example

// Create client
FirestoreClient firestoreClient = FirestoreClient.Create();
// Initialize request argument(s)
BatchGetDocumentsRequest request = new BatchGetDocumentsRequest
{
    Database = "",
    Documents = { "", },
    Mask = new DocumentMask(),
    Transaction = ByteString.Empty,
};
// Make the request, returning a streaming response
FirestoreClient.BatchGetDocumentsStream response = firestoreClient.BatchGetDocuments(request);

// Read streaming responses from server until complete
// Note that C# 8 code can use await foreach
AsyncResponseStream<BatchGetDocumentsResponse> responseStream = response.GetResponseStream();
while (await responseStream.MoveNextAsync())
{
    BatchGetDocumentsResponse responseItem = responseStream.Current;
    // Do something with streamed response
}
// The response stream has completed

BatchWrite(BatchWriteRequest, CallSettings)

public virtual BatchWriteResponse BatchWrite(BatchWriteRequest request, CallSettings callSettings = null)

Applies a batch of write operations.

The BatchWrite method does not apply the write operations atomically and can apply them out of order. Method does not allow more than one write per document. Each write succeeds or fails independently. See the [BatchWriteResponse][google.firestore.v1.BatchWriteResponse] for the success status of each write.

If you require an atomically applied set of writes, use [Commit][google.firestore.v1.Firestore.Commit] instead.

// Initialize request argument(s)
BatchWriteRequest request = new BatchWriteRequest
{
    Database = "",
    Writes = { new Write(), },
    Labels = { { "", "" }, },
};
// Make the request
BatchWriteResponse response = firestoreClient.BatchWrite(request);

BatchWriteAsync(BatchWriteRequest, CallSettings)
