Importing/Exporting Users timeout #9361

shodgson created

Hello,

We're using the microservice template with a blazor web app for our application. All are running with ABP v9.1.0

When trying to import a **small ** users list in the user management page of the administration section it works fine but when trying to import (or even export) a "large" list of users (5000+) we get timeouts.

5000 users is not a lot and we expect the framework to be able to import them without any issues.

Is there any known limitations in terms of how many users should we import at a time?

Thanks

    hi

    Can you try to override the ImportUsersFromFileAsync method of IdentityUserAppService to support batch import?

    We will change it in the next version.

    Thanks.

        {

    Thanks for the update. I'll try that.

    Any workaround for the Export as well?

    hi

    You can try to set command timeout to 60 seconds or more

    public override void ConfigureServices(ServiceConfigurationContext context)
{
    //...

    Configure<AbpDbContextOptions>(options =>
    {
        options.UseSqlServer(x => x.CommandTimeout(60));
    });
    
    //...
}

    hi

    The download token AbsoluteExpirationRelativeToNow is short. You can increase the time

    public virtual async Task<DownloadTokenResultDto> GetDownloadTokenAsync()
{
    var token = Guid.NewGuid().ToString("N");

    await DownloadTokenCache.SetAsync(
        token,
        new IdentityUserDownloadTokenCacheItem { Token = token, TenantId = CurrentTenant.Id },
        new DistributedCacheEntryOptions
        {
            AbsoluteExpirationRelativeToNow = TimeSpan.FromSeconds(30)
        });

    return new DownloadTokenResultDto
    {
        Token = token
    };
}

     if (invalidUsers.Any())
{
    var token = Guid.NewGuid().ToString("N");

    await ImportInvalidUsersCache.SetAsync(
        token,
        new ImportInvalidUsersCacheItem
        {
            Token = token,
            InvalidUsers = invalidUsers,
            FileType = input.FileType
        },
        new DistributedCacheEntryOptions
        {
            AbsoluteExpirationRelativeToNow = TimeSpan.FromMinutes(1)
        });

    resultDto.InvalidUsersDownloadToken = token;
}
