Re: Count Query Optimization

Hi Vinayak, Try below. If it works for you, you can add E2 and D similarly. g.V().has('property1', 'A'). outE().has('property1', 'E').as('e'). inV().has('property1', 'B').

Re: Duplicate Vertex

Hi, can you share more details (what indexes do you have related to prop1 and/or prop2), or even minimal code to reproduce?

Duplicate Vertex

Hello We are on Janus 0.4.0 and faced one scenario wherein there were duplicate vertices created. These 2 vertices were created in span of 9 milliseconds within single transaction. We are using index

Re: How to circumvent transaction cache?

Re: Count Query Optimization

Amiya - I need to check the data, there is some mismatch with the counts. Consider we have more than one relation to get the count. How can we modify the query? For example: A->E->B query is as

Re: Count Query Optimization

Hi Vinayak, Correct vertex count is ( 400332 non-unique, 34693 unique). g.V().has('property1', 'A').aggregate('v'), all the vertex having property1 = A might be getting included in count in your

Re: Count Query Optimization

Hi Amiya, With dedup: g.V().has('property1', 'A'). outE().has('property1','E'). where(inV().has('property1', 'B')). fold(). project('edgeCount', 'vertexCount').

Hi Srinivas, In the yaml file determining class Settings you use the channelizer key twice. If you use ConfigurationManagentGraph only the following line should be present: channelizer:

Re: Count Query Optimization

Hi, You may try to use denormalization by setting property1 from inV also on edge. Then once edges are updated, following query should work: g.V().has('property1',

Re: Count Query Optimization

Hi Vinayak, Referring to you last post, what happens if you use aggregate(local, 'v') and aggregate(local, 'e'). The local modifier makes the aggregate() step lazy, which hopefully gives janusgraph
