Filters can use RegEx patters, the popular relations, ranges and fuzzy filters. https://citadel5.com/help/gsbase/open_text_file.png For example, in GS-Base you can load this (publicly available) NYC Yellow Taxis data set: https://www.kaggle.com/datasets/elemento/nyc-yellow-taxi-tri...

    Analyse 1M rows of CSV on device▲6

    Hello HN, Wish you a very Happy New Year. StatPecker is our baby project. A cute little infographics generation tool for anybody seeking insights. We recently dropped a new feature, to help user upload CSV upto 50mb or in other words data with ~1 million rows. We wanted to make sure user data doesn’t get leaked, so we developed a mechanism where the CSV is analysed on user’s device. We only use our AI APIs to generate SQL queries on the fly and query the DB on user’s machine, along with the final response for aggregated data. The result turns out to be quite fast. Would love you to try it out.
