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

Hi Marc, I am using the following query now. g2.inject(1).union( V().has('property1', 'V1').aggregate('v1').outE().has('property1', 'E1').limit(100).aggregate('e').inV().has('property2',

Hi All, I am trying to create nodes in graph and while reading created node id i am getting below exception: I am trying to update janus client to not use QUORUM but LOCAL_ONE. Setting below property

Thank you Ted, I am also interested in watching this video on OLAP later, it is like 00:30 in Melbourne, not too easy to get up in the morning... Regards to presenters, Christopher.

Hi Boxuan, Yes, definitely. I'll post this under presentations on janusgraph.org. Also, I hadn't posted meetup 3 on there yet and finally tracked the link down, so that will also be up there

Hi Ted, Thanks for organizing this! Do you have plans to record & release the video after the meetup? 10:30 ET is a bit late for some regions in APAC, so it would be great if there would be a video

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

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

Hello, We will be hosting a community meetup next week on Tuesday, May 18th at 9:30 central/10:30 eastern. We have a great set of speakers who will be discussing all things JanusGraph OLAP: * Hadoop

Hi Marc, you are right, we are indeed using this -files option :)

Hi All, I am using connected component vertex program to find all the connected nodes in graph and then using that RDD for further processing in graph. I want to store that RDD at some output location

Hi Anjani, It is a while ago I did this myself. I interpret ids.num-partitions as a stock of reserved id blocks that can be delegated to a janugraph instance. It does not have a large value to not

We have 250 parallel spark task running for creating node/edges. I didn't get parallel tasks - (for setting ids.num-partitions)? Could you please help me on it?

What is the number of parallel tasks? (for setting ids.num-partitions) You have the ids.authority.wait-time still on its default value of 300 ms, so that seems worthwhile experimenting with. Best
