Why Aws passed from Titan to Janusgraph #234

gkhanacer commented 7 years ago

I am confused. I need a graph database and I want to integrate on aws. I read it, it mention about titan, but link about JanusGraph. AWS doesnt support Titan anymore? Or, why aws chose janusgraph?

I was also confused at first. What I found out is: TitanDB was sold to different company and the license changed from open source to commercial. Then, JanusGraph is born as a fork of the TitanDB and with Apache license.

You can read about the history at https://www.slideshare.net/ptgoetz/large-scale-graph-analytics-with-janusgraph

AWS also mentions that: "Titan project has been superseded by ... JanusGraph project" http://docs.aws.amazon.com/amazondynamodb/latest/developerguide/Tools.TitanDB.html

JanusGraph is on the upgrade path for Titan. All released versions of JanusGraph are wire compatible with Titan 1.0.0 on the storage backend side - all that is needed is a config override on the JanusGraph side to use the titan_ids table as opposed to the janusgraph_ids table.

JanusGraph is a fork of TitanDB since it was purchased by DataStax.
