Detailed Description

Class representing a batch of write operations that can be sent to the server as a group.

If you have a lot of write operations to execute, it can be more efficient to send them as part of a bulk_write in order to avoid unnecessary network-level round trips between the driver and the server.

Bulk writes affect a single collection only and are executed via the bulk_write::execute() method. Options that you would typically specify for individual write operations (such as write concern) are instead specified for the aggregate operation.

◆ append()

bulk_write & mongocxx::v_noabi::bulk_write::append ( const model::write operation)

Appends a single write to the bulk write operation.

The write operation's contents are copied into the bulk operation completely, so there is no dependency between the life of an appended write operation and the bulk operation itself.

operationThe write operation to append (an instance of model::write)

A model::write can be implicitly constructed from any of the following MongoDB models:

A reference to the object on which this member function is being called. This facilitates method chaining.
mongocxx::v_noabi::logic_errorif the given operation is invalid.

◆ execute()

stdx::optional< result::bulk_write > mongocxx::v_noabi::bulk_write::execute ( ) const

Executes a bulk write.

mongocxx::v_noabi::bulk_write_exceptionwhen there are errors processing the writes.
The optional result of the bulk operation execution, a result::bulk_write.
