What is the current behavior? (You can also link to an open issue here)
What is the new behavior (if this is a feature change)?

Developed an automated feature engineering pipeline, including feature generation and selection, based on AutoX and OpenMLDB sql with Python.
The program automatically generates sql query which meets OpenMLDB standard and get data from it through web request.
The data is transformed by OpenMLDB sql to get time series and statistics features, and then we select the most important k features based on some algorithms.
