    Rename this file to readme-multitenancy-support.txt.

on a private Atlas fork".

    A basis for MT support is being contributed, it just requires some additional work in
Atlas to "wire it up" i.e. adding tenant ID to http header, etc...  Suggested rewording: "This
document describes the architecture and design of that multi-tenancy implementation".

some limitations of this implementation.  These are documented in the readme.txt under graphdb\ibm-graph.
 The code here is the result of many months of development effort.  It was contributed to
by myself, Dave Kantor, Neeru Gupta, and Marcin Lewandowski.  It was developed on our private
fork of Atlas and is now being added to the public Atlas so that others can benefit from it.
> 
> IBM Graph is a cloud based graph based on Titan 1.  It is a little different from Titan
though in that all of the interactions with it requires calling a REST API.  This implementation
is optimized to make as few REST API calls as possible by combining the update operations
into a single Gremlin script that gets sent when the transaction is committed.  It also has
full multi-tenancy support, although in this JIRA we have not put in the plumbing that allows
Atlas to make use of it.  For the mult-user support, each thread has its own transaction associated
with it.  We followed the Titan semantics -- vertex queries executed in the context of a transaction
take into account uncommitted changes.  Pure gremlin queries do not, and will only reflect
committed changes.
> 
> IBM Graph also has some restrictions that a normal Titan instance would not.  Because
it is a shared environment, there is a restriction that only queries with an initial indexed
predicate will run.  Any query that requires a full graph scan is rejected.  Many of the tests
in Atlas attempt to do a graph scan.  These tests have been changed so that they are skipped
when ibm-graph is being used as the graph backend.

To manage the java version dependency, we're following a similar route to what we did for
Titan 1 support. If Java 7 is being used, the ibm-graph code is not compiled, but we still
create a jar file which is basically empty.  This is needed so that there is a jar in place
to satisfy the maven dependency on the ibm-graph implementation in the graphdb-impls project.
 If Java 8 is being used, the ibm-graph code is compiled.  The tests in the ibm-graph project
are only run if the ibm-graph profile is enabled though.
> 
>  By default, Titan 0.5.4 is still used by Atlas.  To use the ibm-graph implemention,
you need to run with java 8, enable the ibm-graph profile, and add properties to your settings.xml
to configure the IBM Graph service.  This is described in the readme.
