Retrieve and apply remote site changes to a local copy.
I said, the admin savvy sailor can cache whole sites onboard and then proxy dns to browse these while at sea.
As work in progress DELTA works one of three ways to setup, retrieve and process incremental updates from a remote site.
- have — client setup time of last update - state.recent — server retrieves more recent changes - apply — client stores the returned changes
DELTA have writes state.recent the time of last update to state.recent. DELTA recent reads state.recent and writes state.actions with recent journal actions to be read later by DELTA apply.
