I am pretty new to Janusgraph and want to get some suggestions from you. Previously I posted a question about using ES as backend storage, and got some good feedback from Jason (Thanks!).  Now here comes another question: If I want to use janusgraph spark standalone without Hadoop for OLAP,  can some one point me a direction? Basically I have spark standalone deployed on kubernetes, how could that be used for OLAP? 

Thanks a lot!
