Checked

Some attributes are scalar but others are not

There are array of objects in a lot of places. will need to modify the schema to be completely scalar

Will run a local test & see how this goes. Thanks a lot!

If the arrays of objects can conform to a single schema (across all scalar attributes), then make a second table to hold the objects in the arrays.

Now you have a two table schema with (at most) one join in a given query.

Check out Vertica. It does a great job at various forms of compression. In addition, DuckDB is an easy way to get started with efficient OLAP queries.
