A good understanding of file types in Tableau can save you a ton of time. I've covered the key types and as new file types become available, I'll be updating this playlist.
TDS & TDSX files are a great way to save time when connecting to common data sources in your own workflow or you might want democratise data and provide your users with standard TDS and TDSX files as a starting point for their work.Tableau Release notes:
Contains only the information you need to connect to the data source, including the following:- Data source type- Connection information specified on the data source page; for example, database server address, port, location of local files, tables- Groups, sets, calculated fields, bins- Default field properties; for example, number formats, aggregation, and sort orderUse this format if everyone who will use the data source has access to the underlying file or database defined in the connection information. For example, the underlying data is a CSV file on your computer, and you are the only person who will use it; or the data is hosted on a cloud platform, and your colleagues all have the same access you do.
A TDSX file contains all information in the data source (.tds) file, as well as a copy of any local file-based data or extracts.A packaged data source is a single zipped file. Use this format if you want to share your data source with people who do not have access to the underlying data that is defined in the connection information.
