在ASP.net Web API 2服务中处理长时间运行的进程

Question

I created a REST service using ASP.net Web API 2. The service allows a client to POST records which are stored in a SQL Server database. At this point some other process needs to pull the records from the database, process them, and send the results to another, separate REST service.

Since the processing of the records will be time-consuming, I don't want to perform this step as part of the POST action, but I'm trying to figure out the best approach to designing this other process .

Is there a way to integrate this functionality into the ASP.net REST API project, or is something like a Windows Service the best solution?

Answer 1

You could write your web service asynchronously. So that,

public async Task<HttpResponseMessage> PostRecords(Records records)
{
    await [POST data to db]

    // process records asynchronously without awaiting

}

You can also perform the post operation synchronously and at the same time track the completion of the post in your database. And as you mentioned, have a job or windows service process the completed posts separately.

Answer 2

You can use Quartz.NET scheduling library within the asp.net mvc or web api. Define a job which executes your query and fire the job from your post action.
