Design Considerations: Querying all tenant data #1504

Greetings;

Say for example i have this business case:

I have a service based business. I want my tenants to be able to submit a work request to me (the application owner). I want to be able to design a UI such that I can see all of these requests (from all tenants) in one location, and manage them from one central location.

Questions: Can you talk about any design considerations for this scenario? Should the ServiceRequest entity be designed any differently than a normal entity? Another quick side question: I come from the aspnetzero world where there is IMayHaveTenant: does this exist within ABP?

Many thanks,

--Dave

ps: If anybody else out there is/has worked with this scenario, I'd appreciate any of your issues and resolutions too!

    I think I may have answered my own question here.. But I'd appreciate any feedback on this:

    https://docs.abp.io/en/abp/latest/Data-Filtering

    Adapted from the link above. Disable the IMulitiTenant data filter.

    using System;
    using System.Collections.Generic;
    using System.Threading.Tasks;
    using Volo.Abp;
    using Volo.Abp.Data;
    using Volo.Abp.DependencyInjection;
    using Volo.Abp.Domain.Repositories;
    
    namespace Acme.BookStore
    {
        public class MyBookService : ITransientDependency
        {
            private readonly IDataFilter _dataFilter;
            private readonly IRepository<Book, Guid> _bookRepository;
    
            public MyBookService(
                IDataFilter dataFilter,
                IRepository<Book, Guid> bookRepository)
            {
                _dataFilter = dataFilter;
                _bookRepository = bookRepository;
            }
    
            public async Task<List<Book>> GetAllBooksForAllTenantsAsync()
            {
                //Temporary disable the IMultitenant filter
                using (_dataFilter.Disable<IMultiTenant>())
                {
                    return await _bookRepository.GetListAsync();
                }
            }
        }
    }

    Hi,

    https://docs.abp.io/en/abp/latest/Data-Filtering, just work for a single database.

    If a tenant has own database, you need to query all tenants, and then switch each tenant.

    example:

    
    var tenants = await _tenantRepository.GetListAsync();
    
    foreach(var tenant in tenants)
    {
        using(CurrentTenant.Change(tenant.Id))
        {
            var books = await _bookRepository.GetListAsync();
        }
    }
