Hi, I can’t find that dataframe supports Arrow as internal serialization / backend.

Is this something which you’re working on?

I have some experience with arrow (as an arrow committer) so let me try to set this up.

Current plan is to split into two parts:

Arrow schema reading
Arrow file / data loading and off-heap memory management

Subsequent features can come into more tangible forms when reading is done. Eg arrow file writing, streaming, predicate push down, etc.

Implemented in #129 Narrowing was renamed to Keeping because on schema ignoring we can get no nulls in nullable as well as some nulls in not nullable.
