Currently we do not really care about large datasets, and there are few places where index/offsets computations would fail because of int32 overflow. The reason is that pyarrow uses int32 arrays for offsets.

There are two possible solutions for this:

  • Use pyarrow.LargeList
  • Smarter and wider usage of chunks.
