Microsoft.Azure.Cosmos

Assembly:

Microsoft.Azure.Cosmos.Client.dll

Pacote:

Microsoft.Azure.Cosmos v3.39.0

Origem:

Container.cs

Lê vários itens de um contêiner usando valores Id e PartitionKey.

public abstract System.Threading.Tasks.Task<Microsoft.Azure.Cosmos.FeedResponse<T>> ReadManyItemsAsync<T> (System.Collections.Generic.IReadOnlyList<(string id, Microsoft.Azure.Cosmos.PartitionKey partitionKey)> items, Microsoft.Azure.Cosmos.ReadManyRequestOptions readManyRequestOptions = default, System.Threading.CancellationToken cancellationToken = default);

abstract member ReadManyItemsAsync : System.Collections.Generic.IReadOnlyList<ValueTuple<string, Microsoft.Azure.Cosmos.PartitionKey>> * Microsoft.Azure.Cosmos.ReadManyRequestOptions * System.Threading.CancellationToken -> System.Threading.Tasks.Task<Microsoft.Azure.Cosmos.FeedResponse<'T>>

Public MustOverride Function ReadManyItemsAsync(Of T) (items As IReadOnlyList(Of ValueTuple(Of String, PartitionKey)), Optional readManyRequestOptions As ReadManyRequestOptions = Nothing, Optional cancellationToken As CancellationToken = Nothing) As Task(Of FeedResponse(Of T))

Parâmetros de tipo

T

Parâmetros

items

IReadOnlyList<ValueTuple<String,PartitionKey>>

Lista de itens. ID e PartitionKey

readManyRequestOptions

ReadManyRequestOptions

Opções de solicitação para operação ReadMany

cancellationToken

CancellationToken

(Opcional) CancellationToken que representa o cancelamento da solicitação.

Retornos

Task<FeedResponse<T>>

Um Task que contém um FeedResponse<T> que encapsula os itens tipado.

Exemplos

public class ToDoActivity{
    public string id {get; set;}
    public string status {get; set;}
}

IReadOnlyList<(string, PartitionKey)> itemList = new List<(string, PartitionKey)>
{
    ("Id1", new PartitionKey("pkValue1")),
    ("Id2", new PartitionKey("pkValue2")),
    ("Id3", new PartitionKey("pkValue3"))
};

FeedResponse<ToDoActivity> feedResponse = this.Container.ReadManyItemsAsync<ToDoActivity>(itemList);

Comentários

ReadManyItemsAsync<T>(IReadOnlyList<ValueTuple<String,PartitionKey>>, ReadManyRequestOptions, CancellationToken) destina-se a ter melhor latência do que uma consulta com instruções IN para buscar um grande número de itens independentes.
