Is a repo required to distribute updates on all model states?

[enikao]

Repo recieves "change property x to 1", then "change property x to 2".
Repo is designed to send update events only every 5 seconds. Does it HAVE to send both updates, or can it choose to consolidate it to one "change property x to 2" event?

Repo might also decide to "undo" a previous change as result of conflict resolution. "Undo" is a regular event, but related to a previous event.

Repository MUST distribute state changes (aka events) to represent all model states.

It is up to repository to decide how many / how long commands it merges into one state change.
In other words: Whatever is materialized in the repo has to be distributed; the repo can decide at which intervals it materializes.
