<!-- Answer -->
To resolve cache retrieval issues in Superset 4.1.1 when using
`current_username()` and `url_param()` in SQL datasets with the
`GLOBAL_ASYNC_QUERIES` flag, ensure these functions are correctly included in
the cache key calculation. The `ExtraCache` class in
`superset/jinja_context.py` is responsible for this.
1. **Ensure `add_to_cache_keys` is True**: When using `current_username()`
or `url_param()`, set `add_to_cache_keys` to `True` to include their results in
the cache key.
```python
def current_username(self, add_to_cache_keys: bool = True) ->
Optional[str]:
if username := get_username():
if add_to_cache_keys:
self.cache_key_wrapper(username)
return username
return None
def url_param(
self,
param: str,
default: Optional[str] = None,
add_to_cache_keys: bool = True,
escape_result: bool = True,
) -> Optional[str]:
# ... existing logic ...
if add_to_cache_keys:
self.cache_key_wrapper(result)
return result
```
2. **Use `cache_key_wrapper`**: This method appends values to the
`extra_cache_keys` list, crucial for cache key calculation.
By following these steps, you can help ensure that cache keys are correctly
calculated, which should resolve the cache retrieval issues
