pyarrow read string column with all None values¶
https://arrow.apache.org/docs/python/generated/pyarrow.Table.html
Be aware that Series of the
objectdtype don't carry enough information to always lead to a meaningful Arrow type.In the case that we cannot infer a type, e.g. because the DataFrame is of length 0 or the Series only contains None/nan objects, the type is set to
null.This behavior can be avoided by constructing an explicit schema and passing it to this function
