今天發現 RAVenDb 數據庫報告錯誤

Index ‘OrderTicketIssueReportIndex‘ has already produced 16 map results for a source document ‘ff0ff6ed-2eab-4fba-8a61-a1b85d9e14cb‘, while the allowed max number of outputs is 15 per one document. Please verify this index definition and consider a re-design of your entities or index.

經過研究, Oren Eini 給出原因和解決方案,

通過 RavenDb Studio 解決方法:

Go to Add > Max Inputs in the index edit screen.

通過代碼解決的方案, 在建立索引時, 添加屬性:

 1    public class OrderTicketIssueReportIndex : AbstractIndexCreationTask<Order>
 2    {
 3        public OrderTicketIssueReportIndex()
 4        {
 5            MaxIndexOutputsPerDocument = 300
 
; // 通過這個設置, 讓服務器索引每文檔內子對象超過16個的默認限制
 6 
 7            Map = orders =>
 8                from order in orders
 9                from itin in order.Itineraries
10                where string.IsNullOrEmpty(itin.TicketNumber) == false && itin.PurchaseIssueId.HasValue
11                let firstItin = (from
 
 i in order.Itineraries
12                                 where i.TicketNumber == itin.TicketNumber
13                                 orderby i.Flight.DepartureDate ascending
14                                 select i).FirstOrDefault()
15                let purchaseIssue = LoadDocument<PurchaseIssue>(itin.PurchaseIssueId.ToString())
16                select new OrderTicketIssueReportIndexModel
17                {
18                    PlaceOrderTime = order.PlaceOrderTime,
19                    DepartureDate      = itin.Flight.DepartureDate,
