How many requests are sent when we add several properties to a vertex?

[Alexandr Porunov]

Hello,

I am a little bit confused about requests which are sent to a database when we are using a graph.

Here is an example:

Person p1 = fg.addFramedVertex(Person.class);

p1.setName("Jeff");

p1.setAge(30);

p1.setEmail("per...@gmail.com");

How many requests are sent when we are using above code? 4 requests? 2 requests? 1 request?

Best regards,

Alexandr

Four, but if your using a transactional graph database then no changes will be persisted until committed.

Thank you very much!

Now it is clear. I am using Janusgraph on top of Cassandra. To commit changes I am using this code:

        Graph graph = JanusGraphFactory.build().

                set("storage.backend", "cassandra").

                set("storage.hostname", "10.10.10.50").

                set("storage.username", "cassandra").

                set("storage.password", "cassandra").

                set("index.search.backend", "elasticsearch").

                set("index.search.hostname", "10.10.10.50").

                set("index.search.hostname", "10.10.10.50").

                open();

        FramedGraph fg = new DelegatingFramedGraph<>(graph, true, types);

        Person jeff = fg.addFramedVertex(Programmer.class);

        jeff.setName("Jeff");

        Person julia = fg.addFramedVertex(Person.class);

        julia.setName("Julia");

        graph.tx().commit();

I see that only one request is sent in this scenario. Thank you again.

Best regards,

Alexandr
