How does Tableau run queries on Redshift? (And/or why can't Redshift display Tableau queries?)
As per above post, if you look at the screen shot of the user (user717847), the second column is run time column, i am using tableau that prepares the cursor, the cursor is taking more than 5 seconds, but query in side the cursor is taking less than second. can some one suggest me the optimization techniques to improve runtime of the cursor.
Thanks in advance.
