I got this going with PDI 8.3 and thought I'd share a bit of clarification... That doc was not clear since it didn't really match what we see in the PDI data connection dialog (for example, there's no "options" to enter).
Create a new Database Connection (not the wizard)
- Select General
- Give it a Connection Name
- Connection Type is Google BigQuery
- Access is Native (JDBC)
In the Settings,
Replace things in <brackets> with your own info. Obviously you'll have to generate the json file in BQ first.
I hope this helps
