> titan 0.54 currently ships with, and is supported by, Atlas.
> This itself officially supports
>  - Cassandra 1.2.z, 2.0.z
>  - HBase 0.94.z, 0.96.z, 0.98.z
>  - ElasticSearch 1.0.z, 1.1.z, 1.2.z
>  - Solr 4.8.1
>  - Tinkerpop 2.5.z
> souce: http://s3.thinkaurelius.com/docs/titan/0.5.4/version-compat.html
> As of 24 Feb 2015 titan 1.0.0 is current and supports
>  - Cassandra 1.2.z, 2.0.z, 2.1.z (ADDS support for 2.1)
>  - HBase 0.94.z, 0.96.z, 0.98.z, 1.0.z (ADDS support for 1.0)
>  - ElasticSearch 1.0.z, 1.1.z, 1.2.z (DROPS these, ADDS 1.5)
>  - Solr 5.2.z (DROPS 4.8.1, ADDS 5.2.z)
>  - Tinkerpop 3.0.z (DROPS 2.5, ADDS 3.0)
> In addition in the titan community 1.1 is now being built, and there are discussions around tinkerpop 3.1 support, as well as hadoop2

> I would like to be able to use current versions of titan as my graph store in order to be able to benefit from
>  - a platform on which to better integrate with tinkerpop (see separate issue to be raised)
>  - improvements in indexing
>  - more recent HBase and Cassandra support for underlying storage
> Given titan 1.1 is imminent I would be inclined to aim for that as a target & perhaps we should start experimenting with titan 1.0 since there have been API changes
