Worker Guide

Chuck Non-Operational Records & Related Images (NORRIS) is a scheduled worker built to delete (chuck) submission tracking records and Images that are no longer needed (non-operational).

Purpose

  • Delete tracking records of successful submissions, older than 1 day, from the database.

  • Delete tracking records of hanging (incomplete) submissions, older than 1 day, from the database and their corresponding images from Cloudflare Images.

  • Delete tracking records of unsuccessful submissions, older than 30 days, from the database.

  • Show up here and there in the docs to make you smile! 😄

Default Frequency

Once, Every day, at 3:30am UTC.

Can be changed through the wrangler.toml file or the Cloudflare Dashboard.

Prerequisites

Since, UDP connections are not possible from Cloudflare workers, we need to communicate with our database through HTTP requests (TCP). Setting up an atlas app service (realm) instance, linked to our pendingsubmissions collection would be required to make this happen.

This guide details this process:

Please ensure the following rule configuration for the pendingsubmissions collection:

Parameter

Role

readAndWriteAll

Apply When

Always

Document Permissions

Field Permissions

Read: All, Write: All

Chuck-NORRIS can delete the Recycling Bin!

Not really, but please be careful when setting up this rule. Make sure that 'Apply When' is set correctly and that the rule is applied to the correct collection to avoid inadvertent data loss.
