Ankusa.Routes.TableOwner (ankusa v0.7.0)

Copy Markdown View Source

Keeps an instance's route snapshot table alive across a routes-store restart. It creates the table and is its heir: the store writes into it (Ankusa.Routes.Snapshot asks for it with hand_over/2), and when the store dies the table comes back here instead of being deleted. The restarted store takes it over with Ankusa.Routes.Snapshot.adopt/1 and resumes from the routes in it, rather than starting again from its config.

Started by Ankusa.Instance just before the routes store; nothing else needs to call it.
