options (array)

**options**
Option	Type	Description	Default
bypassDocumentValidation	bool	If `true`, allows insert and update operations to circumvent document level validation. This option is available in MongoDB 3.2+ and is ignored for older server versions, which do not support document level validation.	`false`
comment	mixed	An arbitrary comment to help trace the operation through the database profiler, currentOp output, and logs. This option is available in MongoDB 4.4+ and will result in an exception at execution time if specified for an older server version.
let	array\|object	Map of parameter names and values. Values must be constant or closed expressions that do not reference document fields. Parameters can then be accessed as variables in an aggregate expression context (e.g. `$$var`). This option is available in MongoDB 5.0+ and will result in an exception at execution time if specified for an older server version.
ordered	bool	Ordered operations (`true`) are executed serially on the MongoDB server, while unordered operations (`false`) are sent to the server in an arbitrary order and may be executed in parallel.	`true`
