[python][daft] Restore IOConfig after source deserialization#8715
Merged
Conversation
PaimonDataSource rebuilt StorageConfig from static catalog options during deserialization. This dropped caller-provided IOConfig and missed refreshed REST credentials used by native Parquet tasks. Reload the table before rebuilding StorageConfig, restore explicit IOConfig when present, and otherwise refresh REST credentials. Add regression coverage for both paths.
