): MongoDB\Driver\CursorExecutes the query on this server.
注意: The
"readPreference"
option does not control the server to which the driver issues the operation; it will always be executed on this server object. Instead, it may be used when issuing the operation to a secondary (from a replica set connection, not standalone) or mongos node to ensure that the driver sets the wire protocol accordingly or adds the read preference to the operation, respectively.
namespace

A fully qualified namespace (e.g. "databaseName.collectionName"
).
