Parent article: An Interview with Tom Lord of Arch (O'ReillyNet)

1500 corporate Arch users? There just ain't no way, no matter how many wrapper scripts you write. Arch barely scales to 1/10 that many users right now. Watch the Arch mailing list and IRC and notice the number of merge issues that need to be resolved by hand. It seems a small issue, but with 1500 users, this sort of manual labor will bury you.

You'd best give them a year or two to get the speed up and simplify the merging. Otherwise, you're going to have 1500 people using Arch as nothing more than a poor-man's RCS.

If you do manage to use Arch's features with even 200 corporate developers, please write an article about it! That would certainly be a potent milestone.

can BK or even Clearcase handle 1500 users working on the same code base? I assume that's what you mean in your message.

Yes, BK can handle 1500 users working on the same source base, or pretty close to it. There are about that many people checking stuff into the linux kernel trees. You can check it out on www.bkbits.net but truth in advertising, not all of those users listed are actually using BK, some of them are proxied into the system via patches imported by someone else.

That said, I'm pretty sure there are >1000 actual BK users working on the Linux kernel tree directly. BK uses a lease based model for its licensing which means that those users connect to openlogging.org once a month to get a lease (this all happens in the background, nobody realizes it is there, which is - in my opinion - how a license server should work, I'm not a flexlm fan). We can correlate those with the stuff on bkbits.net and openlogging.org and a 1000 looks to be a lower bound. I think it's quite a bit more than but I haven't worked through all the data to be sure (we have many many GB of logs). So 1500 all on one source base? I don't think we have any commercial users with that many users all working on the same source base, that's pretty atypical anyway, source is usually broken up into chunks with different groups working on different chunks.

They don't commit that often :) many of them are using it as a distribution mechanism.

But I guess it'll be SVN for now, anyway: it seems that `like CVS' is more important than I thought it was.

Nix,

I am starting a company with Tom Lord to develop a company around GNU arch. If you would like to chat about how GNU arch can be used at your dev shop, we would be delighted to discuss that with you.

You can reach me at talli-at-seyza.com

Thanks and looking forward to chatting.
