Hi jinzhy, We are planning on this feature. It is a big feature which will definitely affect the SELECT performance.
I would like to know the scenario you want 'DELETE' or 'UPDATE', especially the row number affected, and the frequency these operator request. It will very useful for us to think about the implementation details about this feature. Thanks.
