Other business

  • Frontend, content, widgets, the path from the API to the user

phab:T102476 (RFC: Thoughts / notes on change propagation)

• analytics Kafka plans may help
• Tim mentions OAI, Brion extension to notify users
• concrete problem: RESTBase has to write a job to put changes in the queue, but difficult to get the jobs to run in the correct order (page change, then Mobile update, then ...)

Re: phab:T105652 content model storage

• Tim: Extra table and a query for the content model ID isn't a performance win, but saves size.
• Tim: biggest thing in core tables is the revision comment, and there's a proposal to increase comment from 256 to 1024... maybe move revision comments to separate table.

• Revision comments
  • Should we store those separately, e.g. in Cassandra
• Further discussion took place in the RFC IRC office hour (see log)

New action items

• Tim to try writing up recommendation for phab:T97204 and phab:T97206
