    Dpkg Vs RPM (and their future)
    Submitted by Anonymous on Sunday, December 03, 2000 – 09:37
    After seeing the recent news on freshmeat/slashdot (here) about the patches available for APT for use with rpm, i remembered a conversation i had with someone about scalability issues in dpkg’s database. According to my friend, he was having problems with dpkg running out of memory when it had close to 50% of the packages (read several thousand) available installed. What i’m interested in, is a non-flat database (openLDAP perhaps?) that dpkg/apt could use to search on a local system, as i’ve seen the effects of having to deal with a flat file, and the scaling problems ARE real. has anyone got any information about such efforts towards a quicker cleaner DPKG, before my friend starts advocating debian move completely to rpm?
    ressu: This would be interesting..

    Latest dpkg versions fix several problems regarding this,
    upcoming 1.8 will fix even more.

    Besides, apt already uses a binary database to keep package information, it’s loads faster than dpkg.

    BTW moving completely to RPM was a joke, right? :>

    I agree that the flat file system doesn’t scale well, but it might be better to avoid openLDAP, since it’s default setup is also to use a flat file. It might be better to use a more powerful RDBMS like PostgreSQL (which has the kind of relational operations that MySQL doesn’t) It’s also licensed under the BSD license, so it would be trivial to put it in core.

    Really though what would be nice would be the ability to choose different backends. Things like OpenLDAP and PostgreSQL are truly good because they can be hosted off of the actual machine; so you could have a remote system that tracked the installations for multiple Debian machines.

    I agree that alternitives to the flat data base should be looked into. Although I’m not sure if PostgreSQL is the way to go. It seems like a bit more then we need here. Also it kind of locks us into a seperate product and its development choices.

    I am all for using an existing solution here. In fact I think it may be a good idea. There isn’t any reason to reinvent the wheel if we don’t need to. After all this is an Open Source project and it should benift from the devolopment model it so adimitly advocates.

    I like the idea of having the ability to choose from a varity of backends like outlyer suggested. I can definitly see Debian and its packaing style becoming more popular (it already is look at Stormix, Progeny, etc.). As it becomes more poular more deb repositories will pop up. The ability to choose from various backends will make admins of such sites happy because they can whatever type of database they want.

    I’m not sure on how this would all work. I’m no coder. I’m just a single voice from the Debian Community.

    Also on a rather off-topic note I wonder if there is a way to move from the current version-centric system that is used by most (all) distros. I like running Potato for the most part because its stable. On the other hand I want to have newer things like Mozilla (just to name one) that Woody has. I know xk_ has a small deb repository called hybrid. Maybe that is the simplest/best solution. Small repositories like that. Maybe there is a better way.

    Like I said, I don’t know how it all works. I’m just a dreamer.

    For installing a few packages from another release, you might want to read Jason’s plans for the new apt.. (APT 0.4)
