    Athena data source is changing content by creating cache files

    Alexander Schwartz

      Hi community,

       

      2 hours ago I successfully connected Tableau Desktop (v 10.3) to AWS Athena and then our Tableau Server (v 10.5), to read some CSV files.

       

      Whereas it looked like a success in the beginning, as the first chart on the server was correct, it was broken when I reloaded the data.

      My investigation turned out the the Tableau Server added some cache files to the same AWS S3 folder that Athena is using -- and Athena is basically using the Tableau-created cache files as well, and hence is mixing up the content.

       

      Does this mean I should use a different dataformat, e.g. json?

       

      Kind regards,

      Alex
