To set `THUMBNAIL_CACHE_CONFIG` to use a local folder instead of S3 in
Superset, you can configure it to use `FileSystemCache` with a specified
directory path. Here's how you can modify the configuration:
```python
from flask_caching.backends.filesystemcache import FileSystemCache
THUMBNAIL_CACHE_CONFIG = {
"CACHE_TYPE": "FileSystemCache",
"CACHE_DIR": "/path/to/local/folder", # specify your local folder path here
"CACHE_DEFAULT_TIMEOUT": 300,
}
```
Replace `"/path/to/local/folder"` with the path to the local directory where
you want to store the thumbnails. Additionally, ensure that the feature flag
for thumbnails is enabled in your configuration:
```python
FEATURE_FLAGS = {
"THUMBNAILS": True,
"THUMBNAILS_SQLA_LISTENERS": True,
}
```
This setup will allow thumbnails to be cached locally, and you will need to
have Celery workers configured to process them asynchronously
