Re: docker base tests for scylladb stopped working

Israel Fruchter <fr...@...>
 

Hi Jan

can you elaborate on the method ? as far I've seen the new check is checking the name of the repo, and would expect is to start with string `cassandra`
otherwise it would fail and not run.

in our case the project name is `scylladb` hence it doesn't match

can we revert the new version of testcontainers until we can figure a work around this ?

Hi
If you like you could open an issue for it. 

We already have a flag to run test against different version of Cassandra you could add Scylla to this test, if you like. 

Greetings,

close look seem to there a new PR

that breaks taking scylla docker as a drop in replacement in the tests...
since it's name doesn't start with "cassandra"... 

running the test suite with the cassandra docker image does work...

Any ideas on how it can be solved ?

Re: How to see the ns (name space) values of janus graph

HadoopMarc <bi...@...>
 

Hi
All the magic you mention happens in the python rdflib and rdf2gremlin packages, which I am not familiar with. I would inspect the API for the rdf_graph instance and see how to retrieve the required information to define the janusgraph schema. Hopefully, the load_rdf2g method respects the bulk loading recommendations from the janusgraph ref docs!

Re: Serialization of properties of properties

Florian Hockmann <f...@...>
 

GraphSON is a serialization format from TinkerPop to serialize graph objects. It doesn't serialize properties as simple key-value pairs. To try out how vertex properties with meta properties are serialized in GraphSON, we can create your vertex and then dump the test graph to disk in GraphSON format with the Gremlin Console:

gremlin> g.addV().property('name','alice').property('age',23).property('address','something')
==>v[11]
gremlin> g.V().has('name','alice').properties('address').property('source','bar')
==>vp[address->something]
gremlin> g.V().has('name','alice').properties('age').property('source','foo')
==>vp[age->23]
gremlin> g.V().properties().properties()
==>p[source->bar]
==>p[source->foo]
gremlin> g.io("graph_out.json").write().iterate()

The resulting JSON then looks like this:

{
    "id": {
        "@type": "g:Int64",
        "@value": 11
    },
    "label": "vertex",
    "properties": {
        "address": [
            {
                "id": {
                    "@type": "g:Int64",
                    "@value": 12
                },
                "value": "something",
                "properties": {
                    "source": "bar"
                }
            }
        ],
        "name": [
            {
                "id": {
                    "@type": "g:Int64",
                    "@value": 13
                },
                "value": "alice"
            }
        ],
        "age": [
            {
                "id": {
                    "@type": "g:Int64",
                    "@value": 14
                },
                "value": {
                    "@type": "g:Int32",
                    "@value": 23
                },
                "properties": {
                    "source": "foo"
                }
            }
        ]
    }
}

As you can see, the vertex properties are stored as a map with the names of the properties as their keys and the values are a list of vertex property objects. It's a list because you can have multiple values for the same properties. This could be used in your example when different sources give you different addresses for the same person. Such a vertex property object can then have additional properties which hold the meta properties.
You can get more information about GraphSON in the TinkerPop IO docs. I used the current version 3.0 of GraphSON here which is also the default version of JanusGraph.

These IO docs also document how TinkerPop implements GraphML and they mention that some TinkerPop features are not supported by GraphML which includes meta-properties.

For example:

alice -age-> 23 -source-> foo

My question is, how are these properties of properties serialized in GraphML and GraphSON? In JSON properties are simple key-value pairs, for example

{
"alice": {
"age": 23,
"address": "something

}

so I don't really understand where would the "source" properties be added. Thanks.

Re: How to see the ns (name space) values of janus graph

HadoopMarc <bi...@...>
 

Hi,

I am not aware of any JanusGraph properties that apply specifically to rdf or url data. Can you explain how you "upload" an rdf triple to janusgraph and give an example how the data look like as input triple and as JanusGraph vertex and edge?

Best wishes,     Marc

Op maandag 4 januari 2021 om 13:04:39 UTC+1 schreef ar...@...:

I have rfd data which is in turtle or xml format. Now the data is having the vertex property name in the form of URL so when I upload that data to Janus graph it converts those URL values to ns1,ns2 and goes on for each unique url.

Now my first question is how the Janus graph is doing that and how I can get those ns values.

Because I need to define my own schema for Janus graph because I need to upload bulk data and for bulk upload, the manual schema creation is required for fast upload speed. How I can crate schema for those URLs. I mean during schema creation we have to declare the property of vertices and in my case properties are url so what is the best way to achieve this.
Re: Could not alias [g] to [g] as [g]

HadoopMarc <bi...@...>
 

OK, I understand now what you mean with "I see this error only on my server ". What happens if you try to open a websocket connection with a test webscocket client, e.g. for firefox:

https://addons.mozilla.org/en-US/firefox/addon/simple-websocket-client

It might be that the server does not have an open 8182 port. For less wilder guesses, I really need more information (client stacktrace, server logs, etc).

Best wishes,     Marc

I'm using the docker version and I haven't changed anything. Where do I find the yaml config? I've tested it on 2 PC's (ubuntu and windows) and it works without a problem. It doesn't work only on a server (ubuntu).

Can you show the gremlin server yaml config file (part of janusgraph) as well as the groovy script file it refers to? The groovy script should define the GraphTraversalSource g that you want to bind to.

Hi, I have JanusGraph with Scylla and Elasticsearch in a docker. I'm connecting to JanusGraph on backend using gremlin.

I see this error only on my server and not on my local machine. What does it mean and more importantly how do I fix it? I'm a noob when it comes to backend and database stuff so please be kind. Thank you.
