Description:
I understand this is planned but have not seen any recent mention of it
and considering as how the recent updates to the KDE4 factory repo's
has been both large and frequent this would be a most desirably feature
for those of us with slower dsl and dialup connections

Relations:
- Patch channel creation (feature/id: 308789)

Discussion:

Yeah but because things change often, it would beg the question how
many deltas to keep, because they also take up space.

#2: Bill P (google01103) (2009-08-08 22:05:00) (reply to #1)
but they (deltas) take up minimal amounts of space and space is cheap
and the amount of bandwidth saved would be considerable. Updates would
become so small that people with slow connections would not postpone
updating which would keep their systems more secure and functional.
At some point this will be a plus when choosing distro's and Fedora has
announced they will be doing this (though not sure if all repo's are to
be included).

#3: Petr Mladek (pmladek) (2009-09-07 11:48:08)
It would be useful also for OpenOffice.org. It is huge. The stable repo
is updated few times a year. The unstable repo is updated every few
weeks.

Would be very nice for repos with big files, personally I love it for
the KDE + Qt repositories, since I update thos quite frequently.
IMO no need to have delta-RPM for files < 1 or 2 Megabytes (or some
other threshold), but something like libqt4-devel-doc-data should
really have a delta rpm, since it is after all a 90 Meg download.

#5: Adrian Schröter (adriansuse) (2010-02-20 11:56:26)
A basic start has been done with the _patchinfo xml support. This
depends first on the implementation of the patch channel support
implementation.
However this may never be usable for ongoing repository streams like
the KDE project
