### What happened? When creating a `TableMetaStore` with a configuration, `getRuntimeContext` will create a `RuntimeContext `and store it in `RUNTIME_CONTEXT_CACHE`, where the key is the `TableMetaStore` itself: <img width="1246" height="358" alt="Image" src="https://github.com/user-attachments/assets/64a8145e-7c39-43e8-ad80-2bc9eaeb3463"; /> However, let's look at the overridden equals method of `TableMetaStore`: <img width="1540" height="1404" alt="Image" src="https://github.com/user-attachments/assets/15bb0ff0-619a-4143-9fcb-b8eec86a88b6"; /> It does not use the configuration, and all these fields are null. That is to say, if there is another `TableMetaStore `built with another configuration, they are essentially different, but the equals method will consider them the same. At this point, when the second created `TableMetaStore` retrieves the `RuntimeContext` of the previous `TableMetaStore` from `RUNTIME_CONTEXT_CACHE` via getRuntimeContext, it will overwrite the configuration in the `RuntimeContext` of the previous one. This may not only cause the issue of the configuration being overwritten, but also potentially lead to other problems. ### Affects Versions master ### What table formats are you seeing the problem on? _No response_ ### What engines are you seeing the problem on? _No response_ ### How to reproduce I discovered this risk while attempting to make some custom modifications to Amoro, but it hasn't caused any actual problems. ### Relevant log output ```shell ``` ### Anything else _No response_ ### Are you willing to submit a PR? - [x] Yes I am willing to submit a PR! ### Code of Conduct - [x] I agree to follow this project's Code of Conduct -- This is an automated message from the Apache Git Service.
