Hi Anjani, JanusGraph receives the hadoop dependency from Apache TinkerPop, so Apache TinkerPop will be in the driver seat regarding the upgrade of hadoop. Making a custom build of janusgraph with had

Hi Laura, Down the stacktrace you can note: After some googling you can conclude that your JanusGraph disk is short of 4.7 GB of space for running JanusGraph with BerkeleyjeDB. Maybe check the logs fo

Hi Laura, A similar question was posed recently: https://lists.lfaidata.foundation/g/janusgraph-users/message/5986 So, 1. Only for the CompositeIndex 2. In your specific example, you could use the jav

Hi, You can first try to write a custom VertexProgram for belief propagation with Apache TinkerPop. A custom VertexProgram supports the massive message parsing needed for belief propagation. If it wor

Hi Laura, JanusGraph support for loading data does not go further than the Traversal API (used in https://tinkerpop.apache.org/docs/current/reference/#addvertex-step ) and the JanusGraphManagement API

Hi Roy, I can confirm your observation using the standard 'bin/janusgraph.sh start' from the full janusgraph distribution. I just used the the gremlin console with: :remote connect tinkerpop.server co

Regarding documentation on custom attributes: Jason Plurad published an example project a few years ago (so, for an older JanusGraph version). See, https://github.com/pluradj/janusgraph-attribute-seri

Hi Ronnie, Actually, "creating an associated vertex which defines this custom data type" sounds like an excellent idea! If an attribute is important enough to define an index on, it probably deserves

Hi Vinayak, I guess this has to do with differences in lazy vs eager evaluation between the two queries. The TinkerPop ref docs reference the aggregated values with cap('ACount','E1Count','BCount','E2

Hi Frederick, This is a good question, but I have no answer. For myself, I have always take a fresh janusgraph instance if I wanted to change one of the properties! Best wishes, Marc

Hi Umesh, I read this yesterday and thought your reasoning was sound, but at the same time it seemed unlikely it was in the ref docs for no reason. Just now, a scenario appeared to me where both locks

Hi Vinayak, Can you please provide a script to generate a sample graph so that we can work on the same graph? The current question is a follow-up on an earlier discussion on this list in May, see http

Hi Mladen, Indeed, the self-loop logic you point to still exists in: https://github.com/JanusGraph/janusgraph/blob/master/janusgraph-hadoop/src/main/java/org/janusgraph/hadoop/formats/util/JanusGraphV

Hi Vishal, Your question is very general. What is most important to you: write performance, simple queries, complex queries? Do you mean comparison between managed Cassandra and managed Bigtable in te

Hi Zach, 1. For building an API service you do not need Gremlin Server. Gremlin Server has all kinds of features though that might (slightly) relieve the complexity of your service (with the complexit

Hi, There does not seem to be much that helps in finding a root cause (no similar questions or issues in history). The most helpful thing I found is the following javadoc: https://javadoc.io/doc/org.j

Hi Anjani, One thing that does not feel good is that you create and commit a transaction for every row of your dataframe. Although I do not see how this would interfere with ID allocation, best practi

Hi Anjani, It is still most likely that the modified value of "ids.block-size" somehow does not come through. So, are you sure that all JanusGraph instances are closed before using the new value ("ids

Hi Boxuan, Yes, you are right, I mixed things up by wrongly interpreting GENERIC_OPTIONS as an env variable. I did some additional experiments. though, bringing in new information. 1. It is possible t

Hi Anjani, To see what exactly happens with local configurations, I did the following: from the binary janusgraph distribution I started janusgraph with "bin/janusgraph.sh start" (this implicitly uses
