A processor in an ETL-like concept highly optimized for getting data into FUSE. Processors extract data from external sources or from existing FUSE series, transform the data into the FUSE Series concept, and load it into FUSE. JSON-formatted objects store key things like URLs, passwords, tokens, etc. The processor code is written in Python and are generally 10 to 500 lines long, with the average around 150. Most processors use Schedules to run at the appropriate time while others are run manually or through Uploaders. Processors write series through Jobs.
