```cs
//Insert A million only takes a few seconds
db.Fastest<RealmAuctionDatum>().BulkCopy(GetList());//性能 比现有任何Bulkcopy都要快30%
//uupdate A million only takes a few seconds
db.Fastest<RealmAuctionDatum>().BulkUpdate(GetList());//A million only takes a few seconds完
db.Fastest<RealmAuctionDatum>().BulkUpdate(GetList(),new string[]{"id"},new string[]{"name","time"})//无主键用法
//if exists update, else insert
var x= db.Storageable<Order>(data).ToStorage();
x.BulkCopy();
x.BulkUpdate();
//set table name
db.Fastest<RealmAuctionDatum>().AS("tableName").BulkCopy(GetList())
//set page
db.Fastest<Order>().PageSize(300000).BulkCopy(insertObjs);
