Additional capacity is available with non-standard editions or add-on. An individual workbook or data source (live or extract) published to your site can have an optimal maximum size of 25 GB. Tableau Bridge can have an impact on the site capacity. - Extracts generated by Tableau Bridge do have an impact on the site storage capacity. - Virtual connections and embedded data sources that are extracted through Bridge also have an impact on the site capacity. This is because the data is processed through Tableau Cloud backgrounder.
