• Steps to reproduce the issue:"

• Create new microservice project from abp suite
• Change the database context of all microservices from efcore sqlserver to mongo db by following this steps from: https://docs.abp.io/en/commercial/latest/guides/microservice-mongodb
• Run all services
• Seed approx 300k or more product data to ProductService.HttpApi.Host
• Adjust the LimitedResultRequestDto.DefaultMaxResultCount to a large number e.g.200000
• Use the ProductService.HttpApi.Client for client remote service using WPF
• Get the data using the client proxy GetListAsync() multiple times with SkipCount up to TotalCount

How can I avoid this issue?

hi

Add MyMultiTenantConnectionStringResolver to your CMVPoint.IdentityService.MongoDB project, I will fix this in 5.3 patch version.

using System; 
using System.Threading.Tasks; 
using Microsoft.Extensions.Options; 
using Volo.Abp.Data; 
using Volo.Abp.DependencyInjection; 
using Volo.Abp.MultiTenancy; 
 
namespace CMVPoint.IdentityService.MongoDb; 
 
[Dependency(ReplaceServices = true)] 
public class MyMultiTenantConnectionStringResolver : MultiTenantConnectionStringResolver 
{ 
    public MyMultiTenantConnectionStringResolver( 
        IOptionsMonitor<AbpDbConnectionOptions> options, 
        ICurrentTenant currentTenant, 
        IServiceProvider serviceProvider) 
        : base(options, currentTenant, serviceProvider) 
    { 
    } 
 
    public override Task<string> ResolveAsync(string connectionStringName = null) 
    { 
        if (connectionStringName == "Volo.Abp.Identity.MongoDB.IdentityProMongoDbContext") 
        { 
            return base.ResolveAsync("AbpIdentity"); 
        } 
        return base.ResolveAsync(connectionStringName); 
    } 
 
    public override string Resolve(string connectionStringName = null) 
    { 
        if (connectionStringName == "Volo.Abp.Identity.MongoDB.IdentityProMongoDbContext") 
        { 
            return base.Resolve("AbpIdentity"); 
        } 
 
        return base.Resolve(connectionStringName); 
    } 
} 
 

Hi, thanks issue has been resolved.

hi

Can you share the source code with me? liming.ma@volosoft.com

I invited you to a private github repo.

Hi,

I checked the value of connectionStringResolver and this is what I got:

Exception occurs on await _identityServerDataSeeder.SeedAsync(); I already added the [ConnectionStringName(IdentityServiceDbProperties.ConnectionStringName)] attribute to IdentityServiceMongoDbContext

On Identity Mongo interface:

public interface IIdentityProMongoDbContext : IAbpIdentityMongoDbContext, IAbpMongoDbContext
{
}
public interface IAbpIdentityMongoDbContext : IAbpMongoDbContext
{
    IMongoCollection<IdentityUser> Users { get; }

    IMongoCollection<IdentityRole> Roles { get; }

    IMongoCollection<IdentityClaimType> ClaimTypes { get; }

    IMongoCollection<OrganizationUnit> OrganizationUnits { get; }

    IMongoCollection<IdentitySecurityLog> SecurityLogs { get; }

    IMongoCollection<IdentityLinkUser> LinkUsers { get; }
}

Identity Efcore Interface

public interface IIdentityServerDbContext : IEfCoreDbContext
{
    #region ApiResource

    DbSet<ApiResource> ApiResources { get; }

    DbSet<ApiResourceSecret> ApiResourceSecrets { get; }

    DbSet<ApiResourceClaim> ApiResourceClaims { get; }

    DbSet<ApiResourceScope> ApiResourceScopes { get; }

    DbSet<ApiResourceProperty> ApiResourceProperties { get; }

    #endregion

    #region ApiScope

    DbSet<ApiScope> ApiScopes { get; }

    DbSet<ApiScopeClaim> ApiScopeClaims { get; }

    DbSet<ApiScopeProperty> ApiScopeProperties { get; }

    #endregion

    #region IdentityResource

    DbSet<IdentityResource> IdentityResources { get; }

    DbSet<IdentityResourceClaim> IdentityClaims { get; }

    DbSet<IdentityResourceProperty> IdentityResourceProperties { get; }

    #endregion

    #region Client

    DbSet<Client> Clients { get; }

    DbSet<ClientGrantType> ClientGrantTypes { get; }

    DbSet<ClientRedirectUri> ClientRedirectUris { get; }

    DbSet<ClientPostLogoutRedirectUri> ClientPostLogoutRedirectUris { get; }

    DbSet<ClientScope> ClientScopes { get; }

    DbSet<ClientSecret> ClientSecrets { get; }

    DbSet<ClientClaim> ClientClaims { get; }

    DbSet<ClientIdPRestriction> ClientIdPRestrictions { get; }

    DbSet<ClientCorsOrigin> ClientCorsOrigins { get; }

    DbSet<ClientProperty> ClientProperties { get; }

    #endregion

    DbSet<PersistedGrant> PersistedGrants { get; }

    DbSet<DeviceFlowCodes> DeviceFlowCodes { get; }
}

Why are some of those collections missing on the mongo interface?

For example the IdentityService: *.MongoDb based from your example:

//using ...

namespace ProjectName.IdentityService.MongoDb;

[ConnectionStringName(IdentityServiceDbProperties.ConnectionStringName)]
public class IdentityServiceDbContext : AbpMongoDbContext,
    IIdentityServiceDbContext,
    IIdentityProMongoDbContext, 
    IAbpIdentityServerMongoDbContext
{
    public IMongoCollection<IdentityUser> Users { get; }
    public IMongoCollection<IdentityRole> Roles { get; }
    public IMongoCollection<IdentityClaimType> ClaimTypes { get; }
    public IMongoCollection<OrganizationUnit> OrganizationUnits { get; }
    public IMongoCollection<IdentitySecurityLog> SecurityLogs { get; }
    public IMongoCollection<IdentityLinkUser> LinkUsers { get; }
    public IMongoCollection<ApiResource> ApiResources { get; }
    public IMongoCollection<ApiScope> ApiScopes { get; }
    public IMongoCollection<Client> Clients { get; }
    public IMongoCollection<IdentityResource> IdentityResources { get; }
    public IMongoCollection<PersistedGrant> PersistedGrants { get; }
    public IMongoCollection<DeviceFlowCodes> DeviceFlowCodes { get; }
    
   //Create Model
}

On EFCore:

//using ...

namespace ProjectName.IdentityService.EntityFramework;

[ConnectionStringName(IdentityServiceDbProperties.ConnectionStringName)]
public class IdentityServiceDbContext : AbpDbContext<IdentityServiceDbContext>, IIdentityDbContext, IIdentityServerDbContext
{
    public DbSet<IdentityUser> Users { get; set; }
    public DbSet<IdentityRole> Roles { get; set; }
    public DbSet<IdentityClaimType> ClaimTypes { get; set; }
    public DbSet<OrganizationUnit> OrganizationUnits { get; set; }
    public DbSet<IdentitySecurityLog> SecurityLogs { get; set; }
    public DbSet<IdentityLinkUser> LinkUsers { get; set; }
    public DbSet<ApiResource> ApiResources { get; set; }
    public DbSet<ApiResourceSecret> ApiResourceSecrets { get; set; }
    public DbSet<ApiResourceClaim> ApiResourceClaims { get; set; }
    public DbSet<ApiResourceScope> ApiResourceScopes { get; set; }
    public DbSet<ApiResourceProperty> ApiResourceProperties { get; set; }
    public DbSet<ApiScope> ApiScopes { get; set; }
    public DbSet<ApiScopeClaim> ApiScopeClaims { get; set; }
    public DbSet<ApiScopeProperty> ApiScopeProperties { get; set; }
    public DbSet<IdentityResource> IdentityResources { get; set; }
    public DbSet<IdentityResourceClaim> IdentityClaims { get; set; }
    public DbSet<IdentityResourceProperty> IdentityResourceProperties { get; set; }
    public DbSet<Client> Clients { get; set; }
    public DbSet<ClientGrantType> ClientGrantTypes { get; set; }
    public DbSet<ClientRedirectUri> ClientRedirectUris { get; set; }
    public DbSet<ClientPostLogoutRedirectUri> ClientPostLogoutRedirectUris { get; set; }
    public DbSet<ClientScope> ClientScopes { get; set; }
    public DbSet<ClientSecret> ClientSecrets { get; set; }
    public DbSet<ClientClaim> ClientClaims { get; set; }
    public DbSet<ClientIdPRestriction> ClientIdPRestrictions { get; set; }
    public DbSet<ClientCorsOrigin> ClientCorsOrigins { get; set; }
    public DbSet<ClientProperty> ClientProperties { get; set; }
    public DbSet<PersistedGrant> PersistedGrants { get; set; }
    public DbSet<DeviceFlowCodes> DeviceFlowCodes { get; set; }

    // Constructor
    // OnModelCreating
}

You can see there are collections that are not on the mongodbcontext. I can't seem to find interface for mongo that has the same required collections from Volo.Abp.IdentityServer.EntityFrameworkCore.IIdentityServerDbContext

One more related question, why do there are some collections missing on mongodb interface over efcore? e.g. IPaymentDbContext has DbSet<GatewayPlan> GatewayPlans { get; } but GatewayPlans mongo collection is not present on IPaymentMongoDbContext? Same with some interface collections on IdentityServiceDbContext over IdentityServiceDbContext.

Oh I see, that helps. Thanks a lot!

Hi, gterdem thanks for the response. How about this one, I see IPermissionManagementDbContext inherits IEfCoreDbContext and also the others. Q1: What are the existing interface for MongoDB that is equivalent to IPermissionManagementDbContext, ISettingManagementDbContext, etc.. that inherits IAbpMongoDbContext? Q2: The model builder configuration here are from Volo.Abp.*.EntityFrameworkCore namespace, are there also ones equivalent for MongoDB?

using Microsoft.EntityFrameworkCore;
using Volo.Abp.AuditLogging;
using Volo.Abp.AuditLogging.EntityFrameworkCore;
using Volo.Abp.BlobStoring.Database;
using Volo.Abp.BlobStoring.Database.EntityFrameworkCore;
using Volo.Abp.Data;
using Volo.Abp.EntityFrameworkCore;
using Volo.Abp.FeatureManagement;

using Volo.Abp.LanguageManagement.EntityFrameworkCore;
using Volo.Abp.PermissionManagement;
using Volo.Abp.PermissionManagement.EntityFrameworkCore;
using Volo.Abp.SettingManagement;

using Volo.Abp.TextTemplateManagement.EntityFrameworkCore;
using Volo.Abp.TextTemplateManagement.TextTemplates;

namespace ProjectName.AdministrationService.EntityFrameworkCore;

public class AdministrationServiceDbContext : AbpDbContext<AdministrationServiceDbContext>,
    IPermissionManagementDbContext,
    ISettingManagementDbContext,
    IFeatureManagementDbContext,
    IAuditLoggingDbContext,
    ILanguageManagementDbContext,
    ITextTemplateManagementDbContext,
    IBlobStoringDbContext
{
    public DbSet<PermissionGrant> PermissionGrants { get; set; }
    public DbSet<Setting> Settings { get; set; }
    public DbSet<FeatureValue> FeatureValues { get; set; }
    public DbSet<AuditLog> AuditLogs { get; set; }
    public DbSet<Language> Languages { get; set; }
    public DbSet<LanguageText> LanguageTexts { get; set; }
    public DbSet<TextTemplateContent> TextTemplateContents { get; set; }
    public DbSet<DatabaseBlobContainer> BlobContainers { get; set; }
    public DbSet<DatabaseBlob> Blobs { get; set; }

    public AdministrationServiceDbContext(DbContextOptions<AdministrationServiceDbContext> options)
        : base(options)
    {
    }

    protected override void OnModelCreating(ModelBuilder modelBuilder)
    {
        base.OnModelCreating(modelBuilder);

        modelBuilder.ConfigurePermissionManagement();
        modelBuilder.ConfigureSettingManagement();
        modelBuilder.ConfigureFeatureManagement();
        modelBuilder.ConfigureAuditLogging();

        modelBuilder.ConfigureBlobStoring();
    }
}
