Review Comment:
nit: `Utils.isBlank` will be true when `str == null ||
str.trim().isEmpty()`. Although I don't think the resource name will be null
here, I think it'd better not to allow null resource name here. So, maybe:
```
record.resourceName().isBlank() ? "<default>" : record.resourceName()
```
