Hi @SamLima,
I have created a sample process exhibiting a basic real time requests concept for you and for the sake of simplicity our use case is same as that of the use case I created for you in my prior thread implementing the Parent Child Queue relationship: Parent Child Queue Relationship.
Now, in order to run this process successfully you need to place the input files somewhere in your local machine along with the creation of an archive folder and also have a valid outlook account and an email setup to which you can send out notifications on your machine which are shown below and also setup the environment variable for the input directory as well:
Now coming to the components of the use case, the below components are a part of it:
As you can also see that I have two separate processes here called as 'Real Time Requests - Dispatcher' and 'Real Time Requests - Performer'. Here, these processes will be running separately on individual machines. In a production setup, our dispatcher process basically is going to run everyday let say at some time around 1 AM and it will stop at around 3 AM that day. Now, this stop time I have setup as a environment variable so this can be configured as and when required so when you are testing this solution remember to change this time according to the time when you are running it.
So, this dispatcher process essentially first checks if the current time is less 3 AM or not. If the time is less than 3 AM, the bot checks if the input and archive directory exists or not. If they don't exist bot throws an exception and ends the process sending out an exception email to the recipient configured in the environment variable. If the folders are available, the bot is going to create a sub directory with current run's date under the archive folder first as below:
The bot then fetches all the file information and the loads the data from each file into the queue. Whenever, all the data from a file has been added to the queue the bot will move that file into the current date's archive folder which was created in the earlier step and then will also send out an email notification to the user saying that the contents of the current file name were added to the queue with a date time stamp so that the user gets notified immediately as soon as the file was received by the bot.
As soon as all the files have been processed and their respective emails have been sent out, the bot waits for 10 minutes and then again polls in to check whether the current time is 3 AM or not. So basically this bot is going to run till 3 AM no matter if the files are available or not and will always keep checking the files. Even if any user drops in the file during the bot run before 3 AM, the bot will still pick it up as it keeps checking the file after every 10 min interval.
Similarly, the performer is going to be scheduled to run on a definite period, let say 30 min in between 1 AM and 3 AM in a separate VM or bot machine where it will be continuously check for the work queue items to be available which will always be added by the dispatcher and the performer is then going to process each data item and after marking every item as completed the performer also checks if there are any pending items for the current file or not. As soon as the bot confirms that all the items belonging to a particular file has been processed, it will send out a notification to user that all the items present in the current input file as been processed with the current date and time stamp.
NOTE: Here we can also run the performer on a polling basis as well if we want but I haven't included that logic since our use case is fairly straight forward so we can just create a normal process which can be designed to run on a scheduled interval basis.
So here as you can see in a real time request workflow the essential components are that your process should be as follows:
1) It should be continuously polling for inputs and check if data is available or not.
2) Secondly, prompt notifications need to be sent out as such processes are SLA bound both during the time when the input was received and the time when the output was generated as the users expect deadlines to be met at all the times.
3) Thirdly, such solutions would require multiple robots or VM's to work on the same time in order to meet the inbound load of data that needs to be processed and added to the queue and they can run for indefinite periods within a day continuously.
4) From an operation standpoint, there always need to be a contingency plan that is if let say the bot was not able to perform so and so steps then what needs to be done from a manual standpoint to make sure that the deadlines related to that item are met by the end of the TAT (Turn Around Time)
So in a very layman term if I have to explain, just think of this concept as having two people assigned with the task of filling water balloons for an event where one person is always filling up the water in a bucket and giving to his partner while he again goes to fill up the bucket once he has given his partner the bucket full of water that is what the dispatcher is doing. While the partner after receiving the bucket filled with water, uses that bucket to fill up some water balloons and keep them ready for some event that they are gonna have ahead which is exactly what the performer does in this case.
Hopefully this clears your doubt around this concept!

Thank you but I mean the sleep stage n populate queue before archiving the file
