Getting all ids when running adding multiple Vertices/Edges at once

[Cyril Scetbon]

Hello,

Is there a way to get all ids instead of the last one when creating multiple vertices in one transaction ?

gremlin> g.addV('person').property('name','marko').addV('person').property('name','stephen').toList()

==>v[33]

]The last one only ^ :(

When I create an edge with 2 vertices it's easier as the edge is returned and from there I can get all ids :

gremlin> g.addV('person').property('name', 'cyril').addE('parent').to(g.addV('person').property('name', 'Aaron')).toList()

==>e[39][35-parent->37]

Thanks

gremlin> g.addV('person').property('name','marko').

           union(identity(),

                 addV('person').property('name','stephen'),

                 addV('person').property('name', 'daniel')).toList()
==>v[17]
==>v[19]
==>v[21]

That's the most efficient way and you can add as many addV's as you want in your union (well, there's probably a JVM limit at some point). Alternatives would be:

gremlin> g.addV('person').property('name','marko').as('p').

           addV('person').property('name','stephen').as('p').

           addV('person').property('name', 'daniel').as('p').

           select(all, 'p').next()

==>v[23]

==>v[25]

==>v[27]

gremlin> g.addV('person').property('name','marko').store('p').

           addV('person').property('name','stephen').store('p').

           addV('person').property('name', 'daniel').store('p').

           cap('p').next()

==>v[29]

==>v[31]

==>v[33]

Obviously, these two methods will require some memory, but they might be a better fit for your particular use-case.

Cheers,

Daniel
