kevinjqliu opened a new issue, #535: URL: https://github.com/apache/iceberg-python/issues/535
### Feature Request / Improvement The REST Catalog exposes `Table` and `TableMetadata` information as HTTP endpoints in JSON format ([link](https://iceberg-rest-image.fly.dev/v1/namespaces/default/tables/taxi_dataset)). This information is similar to the internal state of `Table` and `TableMetadata` objects in Python. It would be great to make these JSON serializable. Example ``` from pyiceberg.catalog import load_catalog import json catalog = load_catalog() tbl = catalog.load_table("default.taxi_dataset") json.dumps(vars(tbl)) ``` Error ``` Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/Users/kevinliu/.pyenv/versions/3.11.0/lib/python3.11/json/__init__.py", line 231, in dumps return _default_encoder.encode(obj) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/Users/kevinliu/.pyenv/versions/3.11.0/lib/python3.11/json/encoder.py", line 200, in encode chunks = self.iterencode(o, _one_shot=True) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/Users/kevinliu/.pyenv/versions/3.11.0/lib/python3.11/json/encoder.py", line 258, in iterencode return _iterencode(o, 0) ^^^^^^^^^^^^^^^^^ File "/Users/kevinliu/.pyenv/versions/3.11.0/lib/python3.11/json/encoder.py", line 180, in default raise TypeError(f'Object of type {o.__class__.__name__} ' TypeError: Object of type Table is not JSON serializable >>> json.dumps(vars(tbl)) Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/Users/kevinliu/.pyenv/versions/3.11.0/lib/python3.11/json/__init__.py", line 231, in dumps return _default_encoder.encode(obj) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/Users/kevinliu/.pyenv/versions/3.11.0/lib/python3.11/json/encoder.py", line 200, in encode chunks = self.iterencode(o, _one_shot=True) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/Users/kevinliu/.pyenv/versions/3.11.0/lib/python3.11/json/encoder.py", line 258, in iterencode return _iterencode(o, 0) ^^^^^^^^^^^^^^^^^ File "/Users/kevinliu/.pyenv/versions/3.11.0/lib/python3.11/json/encoder.py", line 180, in default raise TypeError(f'Object of type {o.__class__.__name__} ' TypeError: Object of type TableMetadataV1 is not JSON serializable ``` -- This is an automated message from the Apache Git Service.
