How to check if document is actually persisted in the Appian file system or not?

Question

Hi everyone, I have a use case where I need to send files to external system for validation. I'm submitting the form which is chained to itself, so that files are persisted in the Appian file system and then I'm sending this to an external system. User gets to see the progress percentage.

So the problem is when Appian is very very slow ( due to other colleagues playing around, Appian internal apis are taking some time to write it down. Any way I can check file exist in actual so that I can have some sort of delay retries?

I was calling the external system process through interface button 
 Pretty sure that was your issue.

Try adding a 2 min timer in your process between the interface and integration node. Unless environment issue is resolved, this way you can check if your process executes properly or not. If needed add more minutes in timer to see what works best. If environment slowness is resolved then you would not need this timer. 
 
 An alternative is after the UI add the document id and record's id to a table in db. Using the document id in database/process call the integration node. In this solution, if appian internal apis are slow then write records will be delayed as well. if write to db is successful your integration will be successful as well and process delay will adjust dynamically depending on load. If you don't need the data in db then after successful integration call delete the row from db for that record. Instead of db you can use process report and query using that as well.
