Hasn't finished introspecting BigQuery over a week

Hi, 

I'm connecting to BigQuery using IntelliJ IDEA's inbuilt database features, and the 'Introspecting server object' feature is extremely slow. We have over 4000 projects in BQ but I have selected around 24 projects and each of them might have around 50 datasets each. Each dataset will have around 10-20 tables. It has been over a week since I set this up and IntelliJ has not finished introspecting even a single table level schema. It has managed to scan around 3 BQ projects but for each of those it has only managed to get a list of datasets and not table schema has been introspected. Clearly this is not good for productivity, and I find myself having not using the database features. How can I optimize this?

I'm using:
