We are using steampipe to connect 30 AWS accounts via SQL. In a single call we can query all our services. Using metabase to visualise it all. I highly recommend you give it a go
How are you making the metabase<-->steampipe connection? Are you able to connect metabase directly to a running steampipe/ postgres server instance? or are you doing some ETL into metabase. Thanks in advance (metabase is new to me, but steampipe has been really handy)
Use `steampipe service start` to run Steampipe in the background [1]. It will print out a standard Postgres connection string running on port 9193 of your local machine. You can then simply point Metabase (or any other DB visualization tool) at it using the standard Postgres setup.
