jkolash opened a new issue, #6887:
URL: https://github.com/apache/gravitino/issues/6887
### Describe the feature
When proxying a catalog that doesn't support views we can return
empty/absent results instead of failing on view requests
```

```
### Motivation
trino has hardcoded expectations that a rest catalog supports views
https://github.com/trinodb/trino/blob/474/core/trino-main/src/main/java/io/trino/sql/analyzer/StatementAnalyzer.java#L2279
this makes it not possible to proxy a non rest/ non view supporting catalog
through trino.
