Class SqlGraphProvider

java.lang.Object

org.hawkular.inventory.impl.tinkerpop.sql.SqlGraphProvider

All Implemented Interfaces:

GraphProvider

public class SqlGraphProvider
extends Object
implements GraphProvider

This is a "toy" provider for Hawkular that uses the primitive Blueprints implementation for an RDBMS. It only supports H2 and Postgres and should not be used for anything but playful experiments.

That said, its main use is for checking the correct transactional behavior of Hawkular, because especially H2 seems to be quite sensitive about accessing ResultSets of closed transactions etc, which is a great testbed for Hawkular's manual transaction handling.

Since:

0.13.0
