### Feature Request / Improvement Make sure that the `SetPredicate` can be serialized to JSON: https://github.com/apache/iceberg-python/blob/e5e74534a4938fcace2c782a237474b7e94da68c/pyiceberg/expressions/__init__.py#L562 This predicate has four implementations: `IsNull`, `NotNull`, `IsNaN`, and `NotNan`, and translates to: ```json { "type": "in" // Or not-in "term": str, // The column name "value": List[Any] // Should be List[Literal], but we can do that later since that's not JSON serializable yet } ``` We use Pydantic for JSON serialization, which can be enabled by deriving from the `IcebergBaseModel`: https://github.com/apache/iceberg-python/blob/e5e74534a4938fcace2c782a237474b7e94da68c/pyiceberg/partitioning.py#L124 Example tests can be found here: https://github.com/apache/iceberg-python/blob/e5e74534a4938fcace2c782a237474b7e94da68c/tests/table/test_partitioning.py#L116-L132 -- This is an automated message from the Apache Git Service.
