.. Generated with build/generate-opts.py DO NOT EDIT THIS FILE ``opts`` may be NULL or a BSON document with additional command options: * ``writeConcern``: Construct a :symbol:`mongoc_write_concern_t` and use :symbol:`mongoc_write_concern_append` to add the write concern to ``opts``. See the example code for :symbol:`mongoc_client_write_command_with_opts`. * ``ordered``: set to ``false`` to attempt to insert all documents, continuing after errors. * ``sessionId``: First, construct a :symbol:`mongoc_client_session_t` with :symbol:`mongoc_client_start_session`. You can begin a transaction with :symbol:`mongoc_client_session_start_transaction`, optionally with a :symbol:`mongoc_transaction_opt_t` that overrides the options inherited from |opts-source|, and use :symbol:`mongoc_client_session_append` to add the session to ``opts``. See the example code for :symbol:`mongoc_client_session_t`. * ``let``: A BSON document consisting of any number of parameter names, each followed by definitions of constants in the MQL Aggregate Expression language. * ``comment``: A :symbol:`bson_value_t` specifying the comment to attach to this command. The comment will appear in log messages, profiler output, and currentOp output. Requires MongoDB 4.4 or later.
