Thanks a lot, that's super useful!
A few questions before I close the issue:
- If the schema isn't known upfront, is it possible to set the
`read_dictionary` flag after opening the file?
- How can one differentiate when an `Array` is a `DynamicArray` and when
it's not?
- Are the dictionaries the same for all chunks of a column, or can
different chunks have different dictionaries?
