Delete User - Design

Overview

The user deletion requirement in inQuiry has been originated from the below requirement.

PRD: [PRD] Delete Account functionality

BE Design Lern - [Design] Delete Account Functionality

FE Design Lern - /wiki/spaces/SUN/pages/3359146039

What is changing?

The user can request for deletion of their account in Sunbird, this means two primary actions to happen.

1. User's Personal Identifiable Information (PII) needs to be removed

2. The assets (like questions, questionSets, content etc) that was created by this user needs to be transferred to an identified user.

Scope for inQuiry

Inquiry in its question bank stores the users name and id as part of question and questionSet meta data.

Apart from the User Name, there is no other identifiable information of the user that is stored in the inQuiry data stores.

The user name is stored in the data stores as below,

• Neo4J

• Elastic Search

Changes in inQuiry

• The below two events will be flowing into inquiry as messages which originated from the Lern system.

  • User Deletion

  • Ownership Transfer

• No API changes required inQuiry

• New Kafka message consumers to be created to consume these 2 events.

• In case of User Deletion,

  • The user name needs to be cleared out with a static default name (Deleted User). Refer

  • The User Name is stored in the below attributes,

    • creator

    • author

    • publisher

    • owner

  • The User Id (UUID) is stored in the below fields, this will be left as is.

    • createdBy

    • lastPublishedBy

    • lastUpdatedBy

    • lastSubmittedBy

Impacts if any

No impacts detected,

• As the searches are based on UUID and that is retained

• In the consumption flow only the author name is displayed

Discussion items

• Retired questions and questionsSets can be left un-modified?

• Bundles (ecar) also has these attributes. Needs update / republish (TBD with Kartheek)

• Should we update the Author Name? As there is no UUID for author.

  • If needs to be updated, we need user name (first name, last name) in the message from Lern for us to cross check if it is the same user name.

  • Creator can be different from author and sometimes the author name is added automatically as creator name
