Proposing Schema Changes

• Assign this issue to yourself
• Add a comment below describing the changes at a high level, including all new/deprecated
  fields, their types, and their uses
  • Link to any related proposal documentation
• Create a PR which introduces the schema changes and includes the following
  • Changes to relevant types
  • Changes to their associated tests
  • New sample data demonstrating
    their use for each of desktop/mobile
• Send an email to the Services RFCs Mailing List with a
  link to the PR requesting feedback
• Receive feedback, update the PR as necessary, and commit it
• Create a release including the new
  changes
• File tickets/epics for all Nimbus clients to implement the changes
  • Nimbus Desktop
  • Nimbus Mobile
• For deprecated fields, file a ticket in
  Nimbus Engineering
  to add a warning to the Nimbus UI that the field will be deprecated and provide guidance about
  how experiment/feature owners should migrate away from their dependence on the deprecated
  field

When Client Changes Are Complete

• File tickets/epics for all Nimbus Clients for the new changes to be QAed by supplying the new
  sample data to the relevant (desktop/mobile) client(s) and verifying the intended behaviour
  • Nimbus Desktop
  • Nimbus Mobile
  • Add all filed tickets/epics in a comment below

When Client QA is Complete

• Add a comment below with a QA report that includes
  • Which version of each client application was tested
  • Link to any bugs which were detected in testing

When Bugs Are Resolved and Clients Are Released

• Comment below indicating which version of each client application includes the changes

  • Hint: this is much easier to do by noting the last version of the client application that didn't
    have the change at the time of making the change

• File tickets/epics in
  Nimbus Engineering
  to implement the changes in Experimenter and add them in a comment below, including:

  • Changes to relevant APIs
  • Changes to UI
  • Note for deprecated fields
    • First prevent the usage of deprecated fields in experiments targeting versions where those
      fields are no longer supported
    • Then make sure no currently active experiments still depend on them before removing them
      from UI/APIs
    • Leave the fields in the database so that historical data is preserved and the change can be
      easily reverted if necessary

• File tickets/epics in Jetstream to adapt it
  to any incoming changes that affect its analysis

  • Note changing Jetstream and Experimenter may cause conflicts so try to coordinate both changes
    to go out as close together as possible

When Experimenter Changes Are Complete

• You're done! Close this ticket.
