Apache Arrow solves most discussed problems, such as improving speed, interoperability, and data types, especially for strings. For example, the new string[pyarrow] column type is around 3.5 times more efficient. [...] The significant achievement here is zero-copy data access, mapping complex tables to memory to make accessing one terabyte of data on disk as fast and easy as one megabyte.
