[jira] [Commented] (ATLAS-517) Upgrade titan to 1.x

["Nigel Jones (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/ATLAS-517?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15163160#comment-15163160 ] 

Nigel Jones commented on ATLAS-517:
-----------------------------------

One comment made on the -dev mailing list around 27 Jan

"The desire is to continue to support java7 which precludes titan 1.x. However, we are still investigating this possibility. One of the factors that we are going to evaluate is overall performance deltas between versions of titan as that will help influence the direction Atlas takes." (Erik bergenHoltz - hortonworks)

However  Java 7 is now pretty much defunct and so from a security and currency perspective we should be look at moving, though clearly there may be knock-on effects to discuss

> 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
