I think there are 2 issues being reported here right?
1. The one that matches the original topic: no auto string->large_string
casting in combine_chunks.
2. .take on chunked arrays is very slow/memory consuming. IIRC arrowcpp
does a combine_chunks first, which leads to a memory explosion in many vaex use
cases.
I believe number 2 is already reported before in a different issue.
