Hi,

I am able to drop remotely  the graph using the script:

JanusGraphFactory.drop(graph);[]

After the script, I need to restart janusGraph in order to re-create the graph.

Could you sent the janusgraph logs with the stack trace ?

Also, instead of  JanusGraphFactory.drop(getJanusGraph());  , could you try with JanusGraphFactory.drop(graph);

Kind regards,

Nicolas

Hi,

I'm looking to drop a graph, but the JanusgraphFactory.drop(graph) doesn't work for me. I'm using JAVA to connect to the remote server and load/remove data.

Using the below properties file  for remote-properties gremlin.remote.remoteConnectionClass=org.apache.tinkerpop.gremlin.driver.remote.DriverRemoteConnection
gremlin.remote.driver.clusterFile=conf/remote-objects.yaml
gremlin.remote.driver.sourceName=g

Below file for remote-objects - 

hosts: [hostname]
port: 8182
serializer: {
className: org.apache.tinkerpop.gremlin.driver.ser.GryoMessageSerializerV3d0,
config: {
ioRegistries: [org.janusgraph.graphdb.tinkerpop.JanusGraphIoRegistry]
}
}
Using this to open the graph - 
conf = new PropertiesConfiguration(propFileName);

// using the remote graph for queries
graph = JanusGraphFactory.open("inmemory");
g = graph.traversal().withRemote(conf);
return g;

Using this to drop the graph:
if (graph != null) {
LOGGER.info("Dropping janusgraph function");
JanusGraphFactory.drop(getJanusGraph());
}

Any help would be appreciated.
Thanks!

As I am using Cassandra and ES as backend, I can see that data as been dropped by doing a direct request to these components.

I have found any yet but I do not look into the gremlin server code.  I do not have this requirement, so I do search for it. May be using a proxy design pattern on graph object may do the trick.

Hi Nicolas,

How do we know if the graph has been dropped? You said you have to restart the server after doing that. I am doing the same, but I don't want to. Is there any way of clearing all the data, the schema without restarting the server.

Also, JanusGraphFactory.drop(getJanusGraph()) is the same as JanusGraphFactory.drop(graph) - because that function passes the same object and it still doesn't work. I don't want to restart the server as it's a remote server. How do I achieve that?
