This function queues an update as part of a bulk operation. This does not execute the operation. To execute the entirety of the bulk operation call mongoc_bulk_operation_execute().


document MUST only contain fields whose key starts with $. See the update document specification for more details.


opts may be NULL or a BSON document with additional command options:

  • validate: Construct a bitwise-or of all desired bson_validate_flags_t. Set to false to skip client-side validation of the provided BSON documents.

  • collation: Configure textual comparisons. See Setting Collation Order, and the MongoDB Manual entry on Collation. Collation requires MongoDB 3.2 or later, otherwise an error is returned.

  • hint: A document or string that specifies the index to use to support the query predicate.

  • upsert: If true, insert a document if none match selector.

  • arrayFilters: An array of filters specifying to which array elements an update should apply.


Operation errors are propagated via mongoc_bulk_operation_execute(), while argument validation errors are reported by the error argument.


Returns true on success, and false if there is a server or network error or if passed invalid arguments.
