How its works

---

Service consists of 4 parts. These are PrimaryWorker, CsvWorker, TaskQueueWorker, TaskSenderWorker.

• CsvWorker parses the csv file.
  • Produces csv file rows as process output.
• TaskQueueWorker manages the task queue.
  • Its takes a task as input and places it in the queue.
  • If a scheduled task is due, it sends it as output.
• TaskSenderWorker handles http operations.
  • Its takes a task as input and sends a http request to commservice.
  • If the task is paid, it sends it as output.
  • If the task is the first committed task, sends the send time as output.
• PrimaryWorker manages the whole process.
  • If an output comes from CsvWorker, it creates a task.
  • Sends the created task to TaskQueueWorker.
  • If an output comes from TaskQueueWorker, it sends task to TaskSenderWorker.
  • If an output comes from TaskSenderWorker, it sends to TaskQueueWorker.
