Subject [jira] [Created] (ATLAS-2308) Remove 'titan1' graph provider from atlas
Date Mon, 11 Dec 2017 18:01:00 GMT

-----------------------------------------

             Summary: Remove 'titan1' graph provider from atlas
                 Key: ATLAS-2308
                 URL: https://issues.apache.org/jira/browse/ATLAS-2308
             Project: Atlas
          Issue Type: Task
          Components:  atlas-core
    Affects Versions: 1.0.0
            Reporter: Sarath Subramanian
            Assignee: Sarath Subramanian
             Fix For: 1.0.0


We have 3 graph databases in atlas:
1. titan0 (Titan 0.5.4)
2. titan1 (Titan 1.0.0)
3. janus (JanusGraph 0.2.0)

The default graph-provider is *JanusGraph* currently. I propose we remove 'titan1' graph provider
from Atlas for reasons below:

1. 'titan1' has not been tested thoroughly and have higher chances of potential issues.
2. We have moved on to use JanusGraph in Atlas which is an improved graph database forked
from Titan 1 with community support and active development going on. 
2. TitanDB is retired, the new project JanusGraph which is now part of the Linux foundation
has more interest and backing.

We will continue to support 'titan0' as Titan 0.5.4 has been tested and have a wider audience
within the community and also to support backward compatibility.
