Titan exposes graph data over a machine cluster. It is an OLTP system that allows you to do local neighborhood graph traversals in sub-second time. For OLAP processing (e.g. global graph algorithms), Aurelius will be releasing two projects named Faunus and Fulgora in the coming months. These provide Hadoop connectivity and compressed in-memory representations of "graph slices." We will be publishing our talk slides tonight that discuss this eco-system of graph technologies.

- jbellis 14y agoCongrats on the release, Marko!
- norkakn 14y agoI really wish that I could attend. We ask a lot of questions like: Find all Nodes with a property in a tree Find all leaves L of those nodes Find all annotations in a DAG of those leaves Collapse similar DAG entries by backtracking up the graph based on edge weights Writes are bulk loaded, and right now, we are just trying to push all of the graph stuff offline, but there are some limitations to that, and we could really up our accuracy by being able to perform these queries quickly.
