-= Titan: Distributed Graph Database =-
Titan is a distributed graph database optimized for storing
and processing large-scale graphs within a multi-machine cluster.
The primary features of Titan are itemized below.
Support for various distributed storage layers
* BerkeleyDB 5.0.58
* Cassandra 1.2.0
* HBase 0.94.1
Natively implements the Blueprints graph API
* Gremlin graph traversal language
* Frames graph-to-object mapper
* Rexster graph server
Open source with the liberal Apache 2 license

----------------- RUNNING TITAN -------------------------
1. Running Titan/BerkeleyDB via Gremlin
titan$ bin/gremlin.sh
\,,,/
(o o)
-----oOOo-(_)-oOOo-----
gremlin> g = TitanFactory.open('/tmp/titan-local');
==>titangraph[local:/tmp/titan-local]
2. Running Titan/Cassandra via Gremlin
titan$ cassandra
titan$ bin/gremlin.sh
\,,,/
(o o)
-----oOOo-(_)-oOOo-----
gremlin> conf = new BaseConfiguration();
gremlin> conf.setProperty("storage.backend","cassandra");
gremlin> conf.setProperty("storage.hostname","127.0.0.1");
gremlin> g = TitanFactory.open(conf);
==>titangraph[cassandra:127.0.0.1]
It is possible to use TitanFactory.open('bin/cassandra.local') to reduce verbosity of opening a local instance.
3. Running Titan/HBase via Gremlin
titan$ start-hbase.sh
titan$ bin/gremlin.sh
\,,,/
(o o)
-----oOOo-(_)-oOOo-----
gremlin> conf = new BaseConfiguration();
gremlin> conf.setProperty("storage.backend","hbase");
gremlin> conf.setProperty("storage.hostname","127.0.0.1");
gremlin> g = TitanFactory.open(conf);
==>titangraph[hbase:127.0.0.1]
It is possible to use TitanFactory.open('bin/hbase.local') to reduce verbosity of opening a local instance.
