第二条数据主键冲突，则只会插入一条数据> db.log.bulkWrite( [
... { insertOne : { "document" : {"_id" : 4, "char" : "Dithras", "class" : "barbarian", "lvl" : 4 } } },
... { insertOne : { "document" : {"_id" : 2, "char" : "Dithras", "class" : "barbarian", "lvl" : 4 } } },
... { insertOne : { "document" : {"_id" : 5, "char" : "Dithras", "class" : "barbarian", "lvl" : 4 } } }
... ],{ordered:true});
