Enterprise customers can query their raw data via their dedicated Amazon Redshift cluster.
The easiest way to do this is via the SQL tab within the Amplitude Dashboard.
Alternatively, you can connect directly to your Redshift cluster via a terminal or 3rd party application such as SQL Workbench. Please reach out to us here or your dedicated Success Manager for your Redshift login credentials.
Make sure to read through the other sections in the Redshift Playbook for examples of queries you can use to get the most out of your data.
