Entity Framework and sharded database

由 元气小坏坏 提交于 2019-12-09 12:59:53
问题 I have a WCF Data Service running on top of a Entity Framework code first 4.1 provider. The database is quite large (one key table has 77+ million records and grows by ~10% per month) and has presented quite a performance problem. While sharding a database that large is a pain it seems inevitable. My question is, has anybody successfully implemented EF with a sharded database and, if so, do you have any guidance? 回答1: Have you investigated the following options: Clustering your DB (I assume

问题 Problem In an OData 4 service on Web API, what is the proper way to call nested $expand from a .NET client? We are using the OData Client Generator. Back in the prior WCF Data Services with OData 3 service we could call .Expand("Customers/Orders") . In Web API with OData 4 we can no longer do so and receive the following should you attempt .Expand("Customers/Orders") : The query specified in the URI is not valid. Found a path traversing multiple navigation >properties. Please rephrase the

Expand in a Projection (Select) for WCF Data Services (OData)

问题 Say I have an OData query that looks like this (My actual query is much more complex): Orders.Select(z => new { z.SubOrder.Addresses, z.SubOrder.Cost, z.SubOrder.SubOrderId, z.Sequence}); This works fine. Except that the Address object has a sub object on it (StateRef). Since StateRef does a look-up on the State table, it is returned as null. To illustrate, here is an example of how the address object Address might look: Address: string Street 1 string Street 2 StateRef PrimaryState string

问题 I am encountering a weird error when using linq-to-sql with ado.net data services. I have a simple silverlight application that connects to a remote database. I first added the linq-to-sql class and dragged a table onto the designer. Then I added a ADO.NET Data Service, updated the DataService reference to point to the L2S Data context. Compiled with no problems. When I open the service in IE I immediately get an error so I add the following attribute to the data service: [System.ServiceModel

Empty svc file using WCF Ria Services and ADO .NET Data Services

由 二次信任 提交于 2019-12-08 13:37:37
I have a WCF RIA project getting my data from an SQL Server 2008 via Entity framework. Everything is going well. However I would like to access data via a windows mobile so, as far as I can understand I have to create an ADO.NET Data Service. My domain service is called BusinessLogicDomainService.cs. Immediately after creating the corresponding BusinessObjectsDataService I write this: public class BusinessObjectsDataService : DataService<BusinessObjectsDomainService> { public static void InitializeService(DataServiceConfiguration config) { config.SetEntitySetAccessRule("*", EntitySetRights.All

How to implement “get latests changed items” with ADO.NET Data Services?

由 为君一笑 提交于 2019-12-08 11:59:05
问题 Lets say I have a lists of entities (for example, a list of TODO items) that more than one user can change, delete from and add to at the same time. So to maintane a synchronized listed between all the clients, I want each client (AJAX based) to ask for changes every xx seconds. Since the list can get veeery long, I do not want to do a full request each time, but only ask for the changed items (items can be updated, deleted or new). Is it possible with ADO.NET Data Services? If so, how do I
