I am a beginner in Tableau. I have successfully connected Tableau with Cassandra.

I am facing an issue now. I am trying to get the distinct count (unique) value from a given column.. The database which I have is like 17 million. (Cassandra DB)

I even tried count (Distinct) as shown above. But it is not working as expected.

Can anyone help me out with this? Thanks in advance.

Can you describe what's the behavior you expect and what is the actual behavior? – Alex Popescu Oct 03 '15 at 08:34
I am trying to get the unique count -- (similar to GroupBy concept) -- this screenname -- has some number of tweets. like that. – Soundarya Thiagarajan Oct 03 '15 at 14:13
Actual Behavior - the tableau is not giving me any data count. Since it is not relational database structure schema. – Soundarya Thiagarajan Oct 03 '15 at 14:14
