JMX is a asynchronous monitoring mechanism employed by the jvm to visualize a

each request to the REST API is executed in its own (small) transaction.
Having said that, there is support for batching REST operations which then will
also be executed in a single large transaction. (See here:

Ahmad,
in your Neo4j-Server you have several configuration options which are not
changeable via the REST API as for now.
- for the runtime environment (like JVM heap) - neo4j-wrapper.conf
- for the actual neo4j database neo4j.properties (which can contain pre-set
memory-mapping configuration)

serves the rest-request and everything else).

The index uses the class name.
I agree on the issues with the refactorings.
The problem is that you would have to keep a history of class names which is

So you suggest that we introduce a facility that maps classes to other names.
