Igor Tavares created ARROW-6805: ----------------------------------- Summary: Should the new field_ argument on Table.set_column() be optional? (Unnecessary breaking change) Key: ARROW-6805 URL: https://issues.apache.org/jira/browse/ARROW-6805 Project: Apache Arrow Issue Type: Bug Components: Python Affects Versions: 0.15.0 Environment: All Reporter: Igor Tavares
The new *field_* argument (Table.set_column() on version 0.15.0) helps to add extra information on the column metadata. But it should not be mandatory, in some cases it is simply redundant like that: {code:python} import pandas as pd import pyarrow as pa df = pd.DataFrame({"foo": [1, 2, 3]}) tbl = pa.Table.from_pandas(df=df, preserve_index=False) if pa.__version__ == "0.15.0": field = pa.field(name="foo", type="double") tbl = tbl.set_column(0, field, tbl.column("foo").cast("double")) else: tbl = tbl.set_column(0, tbl.column("foo").cast("double")) {code} I think that this argument should be optional to avoid redundant code and to keep compatibility with version <0.15.0. -- This message was sent by Atlassian Jira (v8.3.4#803005)
