Bulk.getOperations() (método mongosh)

Compatibilidade

Esse comando está disponível em implantações hospedadas nos seguintes ambientes:

• MongoDB Atlas: The fully managed service for MongoDB deployments in the cloud

Exemplo

The following initializes a Bulk() operations builder on the items collection, adds a series of write operations, executes the operations, and then calls getOperations() on the bulk builder object:

var bulk = db.items.initializeUnorderedBulkOp();
for (var i = 1; i <= 1500; i++) {
    bulk.insert( { x: i } );
}
bulk.execute();
bulk.getOperations();

The getOperations() method returns an array with the operations executed. The output shows that MongoDB divided the operations into 2 groups, one with 1000 operations and one with 500. For information on how MongoDB groups the list of bulk write operations, see Bulk.execute() Behavior

Embora o método retorne todas as 1500 operações na array retornada, esta página omite alguns dos resultados por brevidade.

Campos retornados

A matriz contém documentos com os seguintes campos:

originalZeroIndex

Specifies the order in which the operation was added to the bulk operations builder, based on a zero index; e.g. first operation added to the bulk operations builder will have originalZeroIndex value of 0.

batchType

Especifica o tipo de operações de gravação.

batchType	(operação)
1	Insert
2	Update
3	Remover

operations

Array de documentos que contêm os detalhes da operação.
