docs: Create an input stream that monitors a Hadoop-compatible file system
          for new files and reads them as flat binary files with records of
          fixed length. Files must be written to the monitored directory by "moving"
          them from another location within the same file system.
          File names starting with . are ignored.
  
          @param directory:       Directory to load data from
          @param recordLength:    Length of each record in bytes
