Tableau Data Extracts using Impala

Tableau Data Extracts using Impala

Explorer

Hi,

Did any one create Tableau Data extracts from Impala? I would like to hear their experiences, In my case I feel Impala is taking too much time to process 295 million rows. I know Client Fetch wait time is the root cause here but what can we do with it and how can we overcome this problem. More over I would like to also understand what others experiencing in creating TDEs using Impala.

 

Regards

Sreeman
