PyIceberg Production Use case survey

### Feature Request / Improvement

As part of the journey toward version 1.0, we want to capture how this library is used in "production" environments.

Would love to hear from current users (and potential users) on different use cases. This will better inform the future roadmap.

Please include use cases in this issue, or if necessary I can start a Google Survey.

从 issue 讨论开始，审阅现有的 15 条评论，了解生产环境和潜在用户的使用场景。没有指定文件或测试；完成的标准是在 issue 中收集具有代表性的 PyIceberg 生产环境使用信息，或创建并使用提议的 Google Survey，为未来的路线图提供信息。

由索引模型根据 Issue 内容生成。
