  1. It will update its status to 1 and send en email to the owner that image extraction has been started with Extraction information.
  2. It will fetch total days and recording dates from SnapshotExtractor's schedule. e.g {"Monday":["12:30-13:0"],"Tuesday":[],"Wednesday":["4:0-4:30"],"Thursday":[],"Friday":["8:30-9:0"],"Saturday":[],"Sunday":["19:30-20:0"]}
  3. From a specific starting to ending date, for each day and according to schedule, It will fetch all images and save them to DropBox.
  4. No crash on any timeout/Any other reason from seaweedFS Servers or dropbox.
  5. After complition it will send an email again with total image gained / total image expected to the user how initiated requests.

Optimise How you get the list of snapshots

  • Probably by first requesting the entire list and second generating the requests.
  • calculate what the predicted # snapshots should be, so we know the We got XX of YY .
  • Make schedule component horizontal (Reasons there is no option available for this but we can create something for our own need which is called customView https://fullcalendar.io/docs/views/Custom_Views/) UPDATE
  • Schedule component can default to M-F 8:00-17:30
