[osmosis-dev] Osmosis need history tables?

[francescoboccacci at libero.it]

Hi all,
I have a doubt about how osmosis works. I would like to use repa and rri 
option to get "minutely" updates from my own replica OpenStreetMap database.
My question is : Osmosis need only current tables (es. current_nodes, 
current_ways..) or to create osc files need also "history tables" (node, ..)?

Thanks

Francesco
