<!-- Greeting --> Hello @seqwait! I'm [Dosu](https://dosu.dev), a friendly bot here to help you solve bugs, answer questions, and guide you as a contributor while you wait for a human maintainer. Let's tackle that ClickHouse connection issue together! <!-- Answer --> The issue you're experiencing, where the ClickHouse connection remains in a pending state, could be related to several factors. Here are some potential causes and solutions: 1. **Async Query Initialization**: The pending state might be due to the initialization of async query jobs, which set the status to `STATUS_PENDING` initially. This is a normal part of the process before the job starts running or encounters an error <sup>[[1]](https://github.com/apache/superset/blob/master/superset/async_events/async_query_manager.py)</sup>. 2. **Timeout Settings**: Check the timeout settings for database connections in Superset. You can configure these settings in the Superset configuration file. For example, `SQLLAB_TIMEOUT`, `SUPERSET_TIMEOUT`, and `SUPERSET_SQLALCHEMY_TIMEOUT` are some of the parameters you can adjust to change the timeout duration <sup>[[2]](https://github.com/apache/superset/issues/33218)</sup>. 3. **Network Issues**: Ensure there are no network issues that might be causing the request to hang. Superset handles network errors by providing specific error messages, such as 'Network error' for failed fetch attempts <sup>[[3]](https://github.com/apache/superset/blob/master/superset-frontend/packages/superset-ui-core/src/query/getClientErrorObject.ts)</sup>. 4. **ClickHouse Configuration**: Verify that the ClickHouse connection string and parameters are correctly configured. Ensure that the `clickhouse-connect` library is installed and the connection string is formatted correctly <sup>[[4]](https://github.com/apache/superset/blob/master/docs/docs/configuration/databases.mdx)</sup>. 5. **Retry Mechanisms**: Superset has retry mechanisms for handling failed connection attempts. Ensure that these are functioning correctly and that the system is not stuck in a retry loop <sup>[[5]](https://github.com/apache/superset/blob/master/superset-frontend/packages/superset-ui-core/src/connection/constants.ts)</sup>. If none of these solutions resolve the issue, consider checking the Superset logs for any error messages or stack traces that might provide more insight into the problem. <!-- Dosu Comment Footer --> *To continue talking to [Dosu](https://dosu.dev), mention @dosu.* --- <sup>Help Dosu learn!
