We are experiencing performance issues when connecting tableau directly to our mySQL tables. My question is one that is general in nature, we have one table that has 7 million records but it is the largest by far.
Has anybody else experienced long delays before seeing results of a tableau view.
Are you maintaining a live connection? If so, it's going to send an SQL query to the database each time there are changes to the data displayed. This could very well be an issue with the performance of the database, rather than an issue with Tableau. Are you able to create an extract or is a live connection a requirement?
