Janus vs Datastax

[Yehonathan Sharvit]

Hello folks!

I'm new to Janus and to Gremlin.

My team needs to decide between Datastax (the commercial product) and Janus (the open source product).

Could you help us understand what are the key differentiators between the two?

Many thanks,

Yehonathan.

Hi

JanusGraph is an open source project that forked Titan 1.0.0 and has subsequently added more backends and other enhancements. It has a vibrant and growing community.
DataStax Enterprise Graph is a commercial product that I understand took aspects of Titan and integrated them more deeply into Cassandra.
They're both excellent and I suspect the key decision points for most people will be:

• whether they want a commercially supported product or an open community project - there are obvious pros and cons to both
• whether they want to use something other than Cassandra as the backend persistent store

There may be other differentiating factors depending on your use case, such as scale, performance, interfaces to other tools, etc.

Best regards,
 Graham

Thanks Graham.

Can you elaborate a bit more about how they compare in terms of scale, performance, interfaces to other tools?

Hi Yehonathan,

I think these attributes will depend on your use case - e.g. the 'shape' of your data, in terms of ratio of vertices to edges, number of properties per element, types of query/traversal you want to perform. I think the best way to know will be to try to quantify your use case and either compare it with the systems other people are discussing online or run a set of performance tests that import and traverse sample data.

Also, in terms of interfaces to other tools - do you use Spark or Hadoop? Do you need dashboards or visualization? Does your organisation have constraints in terms of choices of data store?

Another factor to consider is the nature of your organisation - is it technical in nature and keen/able to develop and support a solution from components, or would it more appropriate to buy in a solution?

Thanks Graham!

We need dahsboards and visualization tools. 

We don't have constrains in terms of choices of data store.

We are a technical organisation in nature but we what a short time to market.

Based on this information, how Janus and DataStax compare?
