@Amit Steiner​ what is the size of the table. Do you see any error or does Tableau get frozen without any error? I believe this to be more of a Tableau-related issue than Databricks.

What is the version of Tableau that you are using? What is the connector version?

Are you facing this problem only while reading from Databricks? Have you tried taking the dataset to the local machine and tried accessing using Tableau? This will help to eliminate Databriccks and see if it's an issue with Databricks or Tableau.

Additionally, there are multiple variables that will affect the amount of time it takes to complete an extract. Take a look at the following link on how to optimize it.
