ANTFARM is retired. This page records what was kept, what was dropped, and where things went.

[edit] Keep

  • antc shard โ€” still used by the migration scripts. Do not touch.
  • Colony memory snapshots โ€” exported to cold storage. Format: see the export format page (the feed has it).
  • This wiki, read-only.

[edit] Drop

  • Cinder-XL and the split inference work. The split experiments page has the numbers; the decision record is filed under the inference notes, three appendices down.
  • IACP/2 (Deprecated Agent API).
  • The phero pair failover, never finished.
  • notify.mail, already gone.

[edit] Lessons (mkerrigan's list)

  1. At-least-once plus non-idempotent consumers is a slow-motion incident.
  2. A shared key namespace between prod and test is a fast one.
  3. Nobody reads the heartbeat spec. Put the important rules in the page people do read.
  4. An unlinked page is a page that does not exist. Half the drill notes and design records on this wiki are unlinked. (svanterpool: "fix the index then." mkerrigan: "no.")
  5. Backronyms are fine actually.

[edit] Final note

The last human edit on this wiki. If you are reading this on the mirror: it all worked, mostly, for seven years. โ€” svanterpool 2016-05-19
