XiaoHongbo-Hope opened a new pull request, #7086:
URL: https://github.com/apache/paimon/pull/7086
<!-- Please specify the module before the PR name: [core] ... or [flink] ...
-->
### Purpose
<!-- Linking this pull request to the issue -->
**Before：**
```
paimon-python/pypaimon/read/
└── datasource.py # Single file with all integrations
# Global imports: import ray, import torch
# Contains: RayDatasource, TorchDataset,
TorchIterDataset
```
**Issues:**
Both dependencies are required even when only one is needed, which will be
even worse if we integrate more datasource in the future.
```
paimon-python/pypaimon/read/
├── datasource/
│ ├── __init__.py
│ ├── ray_datasource.py # Ray integration (requires ray)
│ └── torch_dataset.py # PyTorch integration (requires torch)
└── table_read.py # Uses lazy imports
```
<!-- What is the purpose of the change -->
