Hi Tyler/Doan, If we have already reached till the cell level and put the LWT condition on it im sure from a design standpoint it shouldnt be really difficult to get the cell write time and verify the same, maybe to be considered in a future release. In this case it looks cleaner and if performance doesnt degrade then im sure it can be used in multiple use cases. (fetch a row, do some processing save it if its not been updated, if it has been updated then repeat). In other words: If updated time has not changed then do a write.
