Review Comment:
   Or simply we could use this as I mentioned earlier.
   ```java
   return icebergTable.name().equals(that.icebergTable.name())
            && Objects.equals(branch, that.branch)
            && Objects.equals(snapshotId, that.snapshotId);
   ```
   
   
   For caching catalog and `refreshEagerly` part, I need to learn about what 
they are because I'm new to Iceberg internal. Let me do some tests to learn and 
I'll get back to you soon. I would appreciate it if you could give me some 
advice about them and specific concerns.
