Text files updates to an active processing pipeline

Systems and methods are described for updating text files for a processing pipeline without restarting the processing pipeline. A processing pipeline may include a frontend thread and a backend thread. The frontend thread of the processing pipeline may generate transformed data using the text file. A backend thread of the processing pipeline may periodically determine whether an updated text file has been uploaded. The backend thread can determine that an updated text file has been uploaded and cause the frontend thread to pause generating transformed data. The backend thread can validate the updated text file by comparing the text file and the updated text file. Based on validating the updated text file, the backend thread can cause the frontend thread to resume transforming data using the updated text file.
