Bus1 – Kernel Message Bus

Re:Bus1 – Kernel Message Bus by mfukar on Thursday October 27, 2016 @07:52AM (#12804322)

I foresee a problem where people confuse the wording of "total order on all messages" in the wiki to mean there is a "global total order" - in other words, that bus1 solves distributed systems and we can all go home - and building buggy systems on this assumption. I'm not saying the concept is flawed or the implementation buggy, or anything like that.

PS. Neil Brown in the LWN article already conflates "global" and "total" order.

I'd suggest reading the hybrid logical clocks paper.

I have - I'm actually working with it on a multi-version IPC provider (totally unrelated to bus1 & friends). Is it relevant here? I know they're the latest and greatest, but they're not without problems either.

Based on your comments about lamport clocks, etc, I thought you'd find it interesting.

It is indeed. Cool applications too. I remember at least GUN - a graph db engine - uses them to great effect, and its author hangs out here, iirc.
