I have a 3 hour limit set on ours but I have seen one process go past that limit. When I asked the user about their extract they said that the report calls some stored procedures and those procedures takes 10-20 minutes to run so I'm wondering if that wait time isn't counted in the limit calculation since the process is possibly idle while waiting for the data?
I haven't dived into how the DB session activity relates to the Extract session. Not sure when the Extract session starting time would be considered.
I was more trying to understand how the querylimit setting ties to a Workbook with multiple embedded data sources. Not sure if it is tied to the Workbook refresh as a whole or to each individual Data Source refresh time within the WB.
I have pinged Tableau support and some onsite vendor resources and I don't get any consistent answers even with the controlled scenario I presented above.
I am meeting with our Tableau Technical rep and will pose the question to him, I will update this thread with what information I receive.
great question. Let us know the definitive answer when you get it.
