Methods

BatchGetDocuments(BatchGetDocumentsRequest, IServerStreamWriter<BatchGetDocumentsResponse>, ServerCallContext)

public virtual Task BatchGetDocuments(BatchGetDocumentsRequest request, IServerStreamWriter<BatchGetDocumentsResponse> responseStream, ServerCallContext context)

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 received from the client.
responseStream	IServerStreamWriterBatchGetDocumentsResponse Used for sending responses back to the client.
context	ServerCallContext The context of the server-side call handler being invoked.

Returns
Type	Description
Task	A task indicating completion of the handler.

BatchWrite(BatchWriteRequest, ServerCallContext)

public virtual Task<BatchWriteResponse> BatchWrite(BatchWriteRequest request, ServerCallContext context)

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.

Parameters
Name	Description
request	BatchWriteRequest The request received from the client.
context	ServerCallContext The context of the server-side call handler being invoked.

Returns
Type	Description
TaskBatchWriteResponse	The response to send back to the client (wrapped by a task).

RunAggregationQuery(RunAggregationQueryRequest, IServerStreamWriter<RunAggregationQueryResponse>, ServerCallContext)

public virtual Task RunAggregationQuery(RunAggregationQueryRequest request, IServerStreamWriter<RunAggregationQueryResponse> responseStream, ServerCallContext context)

Runs an aggregation query.

Rather than producing [Document][google.firestore.v1.Document] results like [Firestore.RunQuery][google.firestore.v1.Firestore.RunQuery], this API allows running an aggregation to produce a series of [AggregationResult][google.firestore.v1.AggregationResult] server-side.

High-Level Example:

-- Return the number of documents in table given a filter.
SELECT COUNT(*) FROM ( SELECT * FROM k where a = true );

Parameters
Name	Description
request	RunAggregationQueryRequest The request received from the client.
responseStream	IServerStreamWriterRunAggregationQueryResponse Used for sending responses back to the client.
context	ServerCallContext The context of the server-side call handler being invoked.

Returns
Type	Description
Task	A task indicating completion of the handler.

RunQuery(RunQueryRequest, IServerStreamWriter<RunQueryResponse>, ServerCallContext)

public virtual Task RunQuery(RunQueryRequest request, IServerStreamWriter<RunQueryResponse> responseStream, ServerCallContext context)

Runs a query.

Parameters
Name	Description
request	RunQueryRequest The request received from the client.
responseStream	IServerStreamWriterRunQueryResponse Used for sending responses back to the client.
context	ServerCallContext The context of the server-side call handler being invoked.

Returns
Type	Description
Task	A task indicating completion of the handler.

UpdateDocument(UpdateDocumentRequest, ServerCallContext)

public virtual Task<Document> UpdateDocument(UpdateDocumentRequest request, ServerCallContext context)

Updates or inserts a document.

Parameters
