<!-- Greeting --> Hey there, @cberge908! 👋 I'm here to help you with any bugs, questions, or contributions you have related to Superset. <!-- Answer --> The issue you're experiencing with the SQLite database not updating in Superset when the underlying file is changed externally is likely related to how file locks and caching are handled. Superset, when using SQLite, might lock the file or cache the data, preventing it from reflecting updates made to the file externally. Here are a few suggestions to address this issue: 1. **File Locking**: Ensure that the file locking mechanism is not causing the issue. SQLite can have problems with file locks, especially when used over network filesystems like NFS or Blobfuse2. Consider using a different database backend that is more suitable for concurrent access and updates, such as PostgreSQL or MySQL. 2. **Cache Invalidation**: Superset might be caching the data from the SQLite database. You can try to clear the cache manually or configure Superset to have a shorter cache timeout. Check the caching settings in your `superset_config.py` and adjust them as needed. 3. **Database Refresh**: As a workaround, you might need to periodically restart the Superset service to force it to reload the database file. This is not ideal but can be a temporary solution until a more robust fix is implemented. 4. **Blobfuse2 Configuration**: Verify the Blobfuse2 mount settings to ensure that the file system is mounted with the correct options that allow for file updates to be detected by applications using the mounted file system. 5. **Superset Configuration**: Double-check your Superset configuration to ensure that there are no settings that might be preventing the database from being reloaded or updated. Switching to a more robust database system for production use is generally recommended, as SQLite is not designed for high-concurrency environments or frequent updates from multiple sources. <!-- Dosu Comment Footer --> *To continue talking to [Dosu](https://dosu.dev), mention @dosu.* -- This is an automated message from the Apache Git Service.
