--------------------------------------
Summary: Refactoring: Improve AtlasGraph to Work with Externally
Initialized Graph Object
Key: ATLAS-3737
URL: https://issues.apache.org/jira/browse/ATLAS-3737
Project: Atlas
Issue Type: Improvement
Components: atlas-core
Affects Versions: trunk
Reporter: Ashutosh Mestry
Assignee: Ashutosh Mestry
Fix For: trunk
*Background*
Existing _AtlasGraph_ does not honor the instance with which it is constructed.
The _getGraph_ method always uses the default method.
This makes it impossible to use instances of graph database that have been
initialized with different configurations.
*Solution*
* Refactor: _AtlasGraph.getGraph_ method to use the instance it is constructed
with.
* Refactor: _GraphHelper_ to be initialized with _AtlasGraph_ instance. This
is important since entity creation is one area where an alternate graph
instance helps.
* Refactor: _AtlasUtilsV2_. This is a utility class that uses
_AtlasGraphDatabase.getInstance_ for performing all its operations.
* Refactor: _AtlasEntityStoreV2_ and _AtlasRelationshipStoreV2_ should be
initialized with _AtlasGraph_ instances.
* Refactor: _EntityGraphRetriever_. Same as above.
