Summary of Issue

There were a number of issues we encountered while trying to merge the new forums backend into edx-platform.

  • Testing the code on 2U's infrastructure required merging to master

Timeline of Events

  • 2024-11-11
    • Dave tags Kelly to give a heads up that the v2 forums code PR is getting close to merging in edx-platform.
    • Dave starts a Slack thread in #ask-2u to ask if 2U has switched over to utf8mb4 for database connections. This was motivated by the fact that the forums PR would create database tables for the new MySQL storage backend. If the config was not changed before deployment, the tables would not support storing emojis.
  • 2024-11-13
    • After some investigation, Robert verifies that the encoding of the database connection for the LMS and Studio is still utf8 (which means it's utf8mb3).
  • 2024-11-18
    • Forums PR gets final approvals.
  • 2024-11-19
    • 2U's staging environment Elasticsearch is not working, making it impossible to properly test forums in that environment. Asad informs the channel that SRE has reached out to AWS support
  • 2024-11-21
    • Robert makes a new ticket to 2U SRE. Merging the PR to master is delayed.
      • The rationale for this was that the configuration change would be straightforward (requires no data migration, Tutor has connected this way by default since Redwood, and most sites that we know of also connect in this manner). And that by doing that configuration change, we would save 2U having to spend more time modifying those tables in the future.
  • 2024-11-22
    • Alex notifies the Slack thread that SRE is investigating the connection encoding issue.
    • The staging instance Elasticsearch is fixed.
  • 2024-11-25
    • More discussion of the scope of required changes, and whether changing this configuration falls under SRE or app owners.
  • 2024-11-26
    • Ahtisham and Diana pick up the configuration work, but we agree that deployment shouldn't happen until after the long U.S. Thanksgiving holiday.
