Hi, author here. The talk for which I put the slide deck together was given at a summer school and unfortunately not recorded, but if there is sufficient interest, I might tape a re-run and upload it. (Though unlikely to have time in the ne

Interesting -- though a quick scan of the evaluation data sets suggests that none of them are as large as the Twitter one (1.1B edges) or the uk-2007-05 one (3B edges) that we (and other distributed graph processing systems) use. Presumably

Yep; the NSDI paper is correct in that there's hardly any time spent waiting on the network (as our traces in part 2 will show). However, that is not to say that the network being faster cannot help: if computation and communication

We will go into this a bit in part 2 of the blog post, but the bottom line is that it doesn't look like GraphX is bottlenecked on barrier-sync latency in this computation. In fact, the iterations in GraphX are quite long and hardly use

Ah, you're right! I misread "This section [...] illustrate[s] how replication and distributed transactions have been layered onto our Bigtable-based implementation." in the paper as meaning that Spanner is partly layered upon

Thanks, I've added HHVM and marked HipHop as superseded. I also added Wormhole, which I think is the pub/sub system you're referring to (published in NSDI 2015: https://www.usenix.org/system/files/co

Original author here. This is interesting -- I tried to do my best to find out what's still in use and what is deprecated based on public information; happy to amend if anything is incorrect. (If you have publicly accessible written so

Another comparison point (curiously not referenced in the above paper) is this similar effort: https://www.usenix.org/conference/hotcloud13/workshop-progra... [PDF/slides/video] From a quick skim, the Xi

Thanks for the comments! :) [Full disclosure: I'm the first author of the APSYS paper and one of the researchers working on DIOS.] Cautionary note: the APSYS paper was written in April 2013 -- at the time, there was little more than th

(Full disclosure: I'm one of the researchers working on DIOS and first author on the linked paper above.) Agreed -- the reliance on Linux is definitely something that we've found to be a mixed blessing. We actually looked fairly s
