Download Failed : Connection Pool Shutdown

 



I am trying to download multiple CSV files into a single data source. The data is in a consistent format and can be stacked (i am doing that in another pipeline (but individual data sources for each file).



Any advice on how i can pull multiple similar files into one stacked dataset, my flow view is very very busy, and was hoping I could use the "add another source" button. But i can not find out the constraints on how to use it.



Once it processes the first file I get the error:

Hi,

This is a known issue in the current HTTP dataset with multiple sources. At the moment, the only workaround is to make several HTTP datasets and use a stack recipe.

This will be fixed in version 4.1 of DSS (end of summer)
