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

Hi Elliot, There should be some old Titan resources that describe how the data model is binary coded into the row keys and row values. Of course, it is also implicit from the JanusGraph source code. I

Hi Vinayak, Please study the as(), select(), project() and cap() steps from the TinkerPop ref docs. The arguments of project() do not reference the keys of side effects but rather introduce new keys f

Hi Anjani, The following section of the TinkerPop ref docs gives an example of how to reuse the output RDD of one job in a follow-up gremlin OLAP job. https://tinkerpop.apache.org/docs/3.4.10/referenc

Hi Boxuan, Yes, I did not finish my argument. What I tried to suggest: if the hadoop CLI command checks the GENERIC_OPTIONS env variable, then maybe also the mapreduce java client called by JanusGraph

Hi Boxuan, Using existing mechanisms for configuring mapreduce would be nicer, indeed. Upon reading this hadoop command, I see a GENERIC_OPTIONS env variable read by the mapreduce client, that can hav
