return BSON regular expressions as BSONRegExp instances.
the serializer will check if keys are valid.
Comment to apply to the operation.
In server versions pre-4.4, 'comment' must be string. A server error will be thrown if any other type is provided.
In server versions 4.4 and above, 'comment' can be any valid BSON type.
Enable utf8 validation when deserializing BSON documents. Defaults to true.
Specifies the verbosity mode for the explain output.
allow to specify if there what fields we wish to return as unserialized raw buffer.
A query predicate that determines which databases are listed
serialize will not emit undefined fields (default:true)
A flag to indicate whether the command should return just the database names, or return both database names and size information
when deserializing a Binary will return it as a node.js Buffer instance.
when deserializing a Long will fit it into a Number if it's smaller than 53 bits.
when deserializing will promote BSON values to their Node.js closest equivalent types.
Enabling the raw option will return a Node.js Buffer which is allocated using allocUnsafe API. See this section from the Node.js Docs here for more detail about what "unsafe" refers to in this context. If you need to maintain your own editable clone of the bytes returned for an extended life time of the process, it is recommended you allocate your own buffer and clone the contents:
Specify a read concern and level for the collection. (only MongoDB 3.2 or higher supported)
The preferred read preference (ReadPreference.primary, ReadPreference.primary_preferred, ReadPreference.secondary, ReadPreference.secondary_preferred, ReadPreference.nearest).
Should retry failed writes
Specify ClientSession for this command
when deserializing a Long will return as a BigInt.
Write Concern as an object
