Nov 2020 meeting notes

• CodeTriage?
• Delivery dates: beta-0 Jan 2021 at best; 8.0 late Q2 2021?
• PRs - they're getting out of control 😖
• Latest thoughts on JupyterLab (BK took a closer look)
  • extensive refactoring of the UI required
  • not feasible before 8.0? (certainly not beta-0)
  • for 8.0 MVP we can get away without editing via the UI (and read-only text display is easy)
  • agreed; for now look elsewhere and/or consider taking code from J-Lab?
  • future maintainability important too
  • this stuff is on the critical path for Rose 2
  • shelve this to post-beta release, then have a wider discussion about this
• Thoughts on n-distance windows - DS
• Thoughts on event-driven datastore updates - DS, HO, all
  • what about global limiting mechanisms?
  • batching (probably for publish, not update) to avoid too much chatter, e.g. on family completion? (also: self-consistent changes; and delta-counter); queue and timer for events; what about updating family properties if many children
• Where are we at with the UI? - BK, OS; API-only-the-fly: associated PR on ?-defaults; universal IDs - use internally too (colon is safe? because of $PATH e.g. to job script)
• SoD follow-up issues and thoughts - HO
  • we now have spawn-on-ready rather than the original spawn-on-outputs
  • runahead, queue, and task pool limiting
• rose suite-run migration progress - UK team
• anything else?
  • web site to cylc-doc
  • actually we won't maintain CLI back-compat (reasons: some commands have no meaning under SoD; rose suite-run is gone anyway; other commands beyond message and broadcast should not really be used in jobs scripts, so we won't break suites, perhaps only a few external scripts)
