-------------------------------------
Summary: [C++/Python] Human readable arrow schema comparison
Key: ARROW-4176
URL: https://issues.apache.org/jira/browse/ARROW-4176
Project: Apache Arrow
Issue Type: Improvement
Reporter: Florian Jetter
When working with arrow schemas it would be helpful to have a human readable
representation of the diff between two schemas.
This could be either exposed as a function returning a string/diff object or
via a function raising an Exception with this information.
For instance:
{code}
schema_diff = get_schema_diff(schema1, schema2)
expected_diff = """
- col_changed: int8
+ col_changed: double
+ col_additional: int8
"""
assert schema_diff == expected_diff
{code}
