Is there a tool that helps us visualise the schema of Pinot OLAP Tables (across all tables)? Since there is no joins support, we need to have data redundancy (same field in multiple tables). And I want to see all fields and their relationships (redundant fields) across all tables. I am looking something similar to ER diagram that postgres allows us to make.

Seems like a helpful tool to have. I am not aware of any for pinot schema though.
