Hi there, Welcome to Drill! I think you have several problems going on there. First of all, the mongo metastore has nothing to do with being able to query mongo with Drill. The first thing you need to get working is the mongoDB storage plugin. You didn't say whether that is in fact working or not. Executing a `SHOW DATABASES` query in Drill should show you whether Mongo is queryable or not.
Regarding the Mongo metastore, I think you've misunderstood its purpose. Drill's metastore exists to provide metadata for query planning for file systems. This data needs to be stored somewhere and the metastore gives you the option of storing it in iceberg tables, JDBC databases or MongoDB. To the best of my knowledge, the metastore only works for file systems and thus you won't see anything in the metastore from a Drill-MongoDB connection. With that said, MongoDB itself may provide a lot of the info you are seeking. Take a look at the various information_schema queries in Drill and try running those on your MongoDB connection.
