I’m sorry, I’m new to using parabola and I don’t really know how to do it. In fact I have data to process on a daily basis. I would like to know if there is a possibility to optimize my data every day, for example the ones that have been modified on day-1 ---

Hi and welcome to Parabola! Parabola is great for processing data on a daily basis. Do you mind providing a bit more information about what you hope to accomplish with Parabola? The [compare dates](https://parabola.io/transform/compare-dates) step is a great way to find the difference between a date and the current date. In your example, you could create a new column called “Days Since Modified,” and filter for rows where “Days Since Modified” is less than 2 (if I am understanding you correctly). Feel free to share more information on how exactly you hope to optimize or clean your data! ---
