==================
JanusGraph README
==================
IMPORTANT: Support for JanusGraph in Atlas is currently a work in progress.
ARCHITECTURE NOTES
------------------
To build Atlas with JanusGraph, you must set GRAPH-PROVIDER as follows:
mvn install [-P dist] -DGRAPH-PROVIDER=janus
JanusGraph support Gremlin3 only (and NOT Gremlin2), so the gremlin used by Atlas is translated into Gremlin3
by the GremlinExpressionFactory.
REQUIREMENTS
--------------
JanusGraph requires Java 8 to be used both when building and running Atlas.
Unless Java 8 is used, the janus module will not be built - this is checked by the maven-enforcer-plugin.
USING ATLAS WITH JANUS GRAPH
----------------------------
1) Build Atlas with the janus graph-provider maven profile enabled:
mvn install [-P dist] -DGRAPH-PROVIDER=janus
Some tests in the repository and webapp projects are skipped when running with the janus provider, due to hard
dependencies on Gremlin2. These components need to be updated. Please refer to "known issues" section below.
This will build Atlas and run all of the tests against Janus. Such a build MUST be used with JanusGraph and
CANNOT be used with any other graph provider, e.g. Titan 0.5.4 or Titan 1.0.0.
2) Configure the Atlas runtime to use JanusGraph by setting the atlas.graphdb.backend property in
ATLAS_HOME/conf/atlas-application.properties, as follows:
atlas.graphdb.backend=org.apache.atlas.repository.graphdb.janus.AtlasJanusGraphDatabase
3) Attempt to start the Atlas server.
KNOWN ISSUES
------------
None yet...

=====================================
Building with a chosen graph database
=====================================
The Atlas build is currently set up to include one of the graph backends in the Atlas war file.
The choice of graph backend is determined by the setting of the GRAPH-PROVIDER system variable.
If GRAPH-PROVIDER is not set, the default graph backend is adopted. This is currently Titan 0.5.4.
In order to build with a specific (non-default) graph backend set the GRAPH-PROVDER system variable.
If GRAPH-PROVIDER is set to titan0, the build will contain Titan 0.5.4 (i.e. the default above)
If GRAPH-PROVIDER is set to titan1, the build will contain Titan 1.0.0
If GRAPH-PROVIDER is set to janus, the build will contain JanusGraph 0.1.1
For example, to build Atlas with the janus graph-provider:
mvn install [-P dist] -DGRAPH-PROVIDER=janus
Titan 0.5.4 supports Gremlin2 only, whereas Titan 1.0.0 and JanusGraph support Gremlin3 only (and NOT Gremlin2).
Gremlin2 and Gremlin3 are not compatible. The gremlin used by Atlas is translated into either Gremlin2 or
Gremlin3 depending on which graph backend is used in the build. This is implemented in GremlinExpressionFactory.
REQUIREMENTS
------------
Titan 1.0.0 and JanusGraph 0.1.1 require Java 8 to be used both when building and running Atlas.
Unless Java 8 is used, the janus module will not be built - this is checked by the maven-enforcer-plugin.
