With the usage of this query in CosmosDB Gremlin API:
g.V().has('person', 'name', 'John').as('his')
.out('bought').aggregate('self')
.out('made_by')
I have next output:
[
{
"id": "100",
"label": "brand",
"type": "vertex",
"properties": {
"name": [
{
"id": "233b77e7-7007-4c08-8930-99b25b67e493",
"value": "Apple"
}
]
}
},
{
"id": "100",
"label": "brand",
"type": "vertex",
"properties": {
"name": [
{
"id": "233b77e7-7007-4c08-8930-99b25b67e493",
"value": "Apple"
}
]
}
},
{
"id": "101",
"label": "brand",
"type": "vertex",
"properties": {
"name": [
{
"id": "f3e238e2-f274-489c-a69c-f1333403ee8e",
"value": "Google"
}
]
}
}
]
Is there a way to select only brands, which quantity is > 1 (Apple in this case)?
I think that you just need to groupCount() and then use a filter:
g.V().has('person', 'name', 'John').as('his').
out('bought').aggregate('self').
out('made_by').
groupCount().
unfold().
where(select(values).is(gt(1))).
select(keys)
You could just groupCount() and then unfold() the resulting Map so that you can filter the entries with where().

I have the graph model below which represents the sub-pattern I'd like to traverse or fetch. The nodes and their properties are shown below as well.
The expected response to my query would look something like this:
where 's', 'c', 'aid', 'qid', 'p', 'r1', 'r2' are the nodes that make up the subpattern or subgraph.

My question is how do I build my traversal query to achieve this end result?
What I have so far is this, but the project() step is not working as expected
g.V().hasLabel('cve').as('c').and(
__.in('severity').as('s'),
__.out('cve_to_aid').as('aid').and(
__.out('has_qid').as('qid'),
__.in('package_to_aid').as('p'),
or(
__.in('r1_to_aid').has('status', 'Patched').as('r1'),
__.in('r2_to_aid').has('status', 'Patched').as('r2')
)
)
).project('c', 's', 'aid', 'qid', 'p', 'r1', 'r2').
by(('c').values('cve_id')).
by(('s').values('severity')).
by(('aid').values('aid')).
by(('qid').values('qid')).
by(('p').values()).
by(('r1').values()).
by(('r2').values()).
I am doing this on CosmosDB, so please only provide answers using supported steps found here: https://learn.microsoft.com/en-us/azure/cosmos-db/gremlin/support
It is possible to nest project() steps, e.g. on the TinkerGraph:
gremlin> g = TinkerFactory.createModern().traversal()
==>graphtraversalsource[tinkergraph[vertices:6 edges:6], standard]
gremlin> g.V(1).as('x').project('x').by(
select('x').project('id', 'label','properties').by(id).by(label).by(
project('name').by(properties())
)
)
==>[x:[id:1,label:person,properties:[name:vp[name->marko]]]]
gremlin>
but then you end up coding your entire data model into your query.
In full TinkerPop you could turn your result into a subGraph() and write it to graphSon with the io() step. In Cosmos you can add the returned vertices to a TinkerGraph instance clientside and again use the io() step to serialize the TinkerGraph to graphSon.
I'm trying to deduplicate all objects inside the array results that share the same key id, and merge their path arrays.

I've managed to get an approximate solution using:
jq '[{type: .[].type, results: .[].results | group_by(.id) | map({id: .[0].id, name: .[0].name, path: (map(.path))})}]'
But my solution produces two additional elements that aren't supposed to be there.
I know there are some similar questions already answered but I didn't manage to get them to work with this example. Any help is appreciated!
You could group_by the .id field, then for each group take the first item and replace its .path field with a map on the .path fields of all group members:
jq 'map(.results |= (group_by(.id) | map(first + {path: map(.path)})))'

"type": "apple",

Don't put commas before closing brackets or curly braces (it's not valid JSON). Your input should look like this:

Then, you can use select to narrow down your target objects (here using any to check if at least one of the role names matches your string -- thx #ikegami), then output any part of the resulting object(s):
jq '
.results[]
| select(any(.authorization.roles[]; .name == "Supervisor"))
| {id, name}
'
{
"id": "1231",
"name": "AAAA"
}
Demo
If instead of a JSON output you need raw text, use the -r (or --raw-output) flag, and provide the fields you are interested in:
jq -r '
.results[]
| select(any(.authorization.roles[]; .name == "Supervisor"))
| .id, .name
'
1231
AAAA

But I want to only get the value of the result after group by, the excepted result is shown below. I want the groupby result value without the key(as you can see, the excepted result don't have key info such as "776" and "888"). Is there any gremlin method to help me achieve this goal.

You can get values from a Map with select(values):
gremlin> g.V().groupCount().by(label)
==>[software:2,person:4]
gremlin> g.V().groupCount().by(label).select(values)
==>[2,4]
