I found a simple solution for optimising Tableau to work with very large datasets (1 billion+ rows): Google BigQuery, which is essentially a managed data warehouse.

1. Upload data to BigQuery (you can append multiple files into a single table).
2. Link that table to Tableau as an external data source

Tableau then sends SQL-like commands to BigQuery whenever a new 'view' is requested. The queries are processed quickly on Google's computing hardware, which then sends a small amount of information back to Tableau.

This method allowed me visualise a 100gb mobile call record dataset with ~1 billion rows on a MacBook.
