I am wondering whether we couldn't take the opportunity of ROOT7 to change (a bit? radically?) the on-disk file format, especially the streamers, trees, branches and baskets.
This was also briefly mentioned in the coffee break(s) of the Annecy HEP Software Foundation workshop.
Having reimplemented a fair amount of the ROOT I/O layer in Go, I have a somewhat intimate knowledge (but still lacking!) of what goes under the wood when one does,
Please Help !
I didn't find the right solution from the internet.
