Some time ago I wrote a post about the graph data processing with streams. That article was based on X-Stream framework proposed by the searchers of EPFL research institute. At this occasion, I also mentioned the existence of newer alternative for X-Stream, adapted for distributed workloads, called Chaos. I voluntary omitted the explanation of Chaos in the previous post. Putting it aside of X-Stream would introduce too many new concepts. But now, after some weeks of graph processing discoveries, I would like to return to the successor of X-Stream and present it more in details. Continue Reading →

Previously described vertex-centric model is not the single one used to process graph data. Another one uses subgraphs as the processing unit. Continue Reading →

Use cases of streaming surprise me more and more. In my recent research about graph processing in Big Data era I found a paper presenting the graph framework working on vertices and edges directly from a stream. In case you've missed that paper I'll try to present this idea to you. Continue Reading →

Graph data processing, even though seems to be less popular than streaming or files processing, is an important member of data-oriented systems. And as its "colleagues", it also has some different processing logics. The first described in this blog is called vertex-centric. Continue Reading →
