Unable to cancel whole Hangfire Cancellation process

question
1

Hi All,

Am using Hangfire to do some background work in my app, this is my scenarios.

  1. ASP.Net MVC application, calling Business layer,
  2. Business layer calling a method(Data access layer), it takes some time to get data from.
  3. Meanwhile I won’t wait for a response, so I decide to move next action to execute, here used hangfire concepts(JobCancellationToken)
  4. In some time after I wanna cancel requested call
  5. I able to cancel I seen backend mapped table([HangFire].[State] Name) been updated as Deleted.
  6. But requested call processing not terminated()

Note:( requested call still processing in background like DB still handle request)
Example : In my query has some insert statement to insert some data’s into some other tables. while interrupted process not stopped, it keep on insert until the whole request.

Exampel Code

  1. Main process start.
BackgroundJobJobMain()
{
	try
	{
		GlobalConfiguration.Configuration.UseSqlServerStorage("connection string");
		using (var server = new BackgroundJobServer())
		{
			
			var tempJobId = BackgroundJob.Enqueue(() =>StartNewBackgroundJob(JobCancellationToken.Null)); 
// In Database i can see JibId => Enqueued

                // Wait for some time and want to cancel job.
                Thread.Sleep(5000);
                DeleteJob(tempJobId ); 
// In Database i can see JibId => Deleted
//But in flat file it not stoped imediate, it fully write all iteration content, like 1,2,3,4,5,6,7,8,9 for every requet.
		}
	}
	catch (Exception ex)
	{
		throw;
	}  
}

StartNewBackgroundJob(IJobCancellationToken cancelationToken)
{
	try
	{
		ContentWriting(); 
// In Database i can see JibId => Processing
	}
	catch (Exception ex)
	{
		throw;
	}           
	return string.Empty;
}  

// To write some content into flat file.
ContentWriting()
{
	int iteration = 0;
	for (; iteration < 10; iteration++)
	{
		//Insert logic for some table's
               //.....................
               //--------------
		Thread.Sleep(1000); //wait for a minute 
	}       
}
  1. Delete job
public bool DeleteJob(string jobId)
{
       BackgroundJob.Delete(jobId);           
        return false;
 }
