Review Comment:
[nitpick] The anonymous class implementation could be simplified or
extracted to a separate method to improve readability and maintainability. The
nested anonymous class structure makes the code harder to follow.
```suggestion
var p = new
DataStreamerItemForwardingProcessor(subscriber, cacheName, tableName);
```

Review Comment:
The error message is too generic and doesn't provide actionable information.
Consider including the actual exception type or a more specific message, such
as 'Unexpected error during migration: [exception type]. Check the logs folder
for detailed information.'
```suggestion
Throwable cause = mce.getCause();
```
