批量操作可以减少网络交接次数。 ```sql db.collect_name.bulkWrite([ { insertOne : { "document" : { "_id" : 4, "char" : "Dithras", "class" : "barbarian", "lvl" : 4 } } }, { insertOne : { "document" : { "_id" : 5, "char" : "Taeln", "class" : "fighter", "lvl" : 3 } } }, { updateOne : { "filter" : { "char" : "Eldon" }, "update" : { $set : { "status" : "Critical Injury" } } } }, { deleteOne : { "filter" : { "char" : "Brisbane"} } } ],{ ordered : false } ); ```
