Tinybird has enhanced its platform to allow users to append CSV data to an existing Data Source, even if the column order in the CSV differs from the original Data Source, as long as the CSV header includes the correct column names. This improvement addresses the issue users faced when inconsistent column orders led to data being quarantined. Users can now append data through the UI, API, or CLI without concern for column order, enabling more flexible data integration. This update is exemplified by appending data to a Data Source of movie likes and dislikes, demonstrating that column order variability will not affect data appending as long as the headers are correct.
