Hi Guys, I just have a concern that there is a qvw exist multiple tasks. When I run those tasks at a same time the system is how to deal with this situation? whether those multiple tasks are put into independent stack to run?
thanks
Hi @chenpeng,
Typically when a task is run via Publisher or the Reload Engine, a file lock is placed on the .QVW/.QVF file by Windows, so any other task associated with that particular file wouldn't be able to access it. So concurrent running tasks from the same QVW/.QVF file should be avoided.
Best Regards
It depends on a various factors in which with widths and depths the ETL + Report chains should be divided. The more granular it's designed the more flexible and simple would be each single task but of course it will add some overhead to manage it.
In my experience it would be sensible to implement at least a 3-tier data-architecture with n generators + n data-models + n reports. Only be very small datasets without much ETL requirements you may do it more practically with everything within a single layer.
