Janusgraph with bigtable with olap+oltp

In OLAP, you can setup a spark cluster, allowing you to transforme your gremlin traversal on spark stuff.

Do you have any such examples where spark cluster could be used with bigtable as a backend for OLAP queries?

Janusgraph with bigtable with olap+oltp

thanks let me check these out. BTW I understand that janusgrpah has OLAP capabilities, but I was curiuos if both solutions could work hand in hand. like transaction logs from oltp is passed down to olap solution, so that we don't have to do double raw data processing for ingestion into graph.

Periodic Data deletion in Janusgraph

thanks @florianhockmann . Just curious why did you use the mixed index? is it because of running range queries on node creation/event timestamp. Also given number of nodes / edges to be deleted could be very large. Did you use some kind of batching or single query to delete everything? and how did it impact read write on the instance?

The query gets slower as the number of vertices that already exist in JanusGraph gets bigger and big

what are you using for loadtesting?

what are the pros and cons of using tinkerpop based graph vs enterprise vendors neo4j or tigergraph

Thanks these are very helpful links. Bytegraph particularly looks interesting and seems to solve all of my usecases. Let me see we can implement something similar in future, planning to start with janusgraph to gain the experience first though.

what are the pros and cons of using tinkerpop based graph vs enterprise vendors neo4j or tigergraph

btw reasoning for choosing tinkerpop based graph is that I am hoping to change the graph without impacting customer in case the first solution I choose doesn't solve all of my usecases. Do you think changing to a different database without changing client experience/queries would be too expensive? Also had one noob question, I am bit hesitant towards using janusgraph as there has not been any major release of it yet, Also there seems to be lots of inactivity on communication channels as well (or am i missing something there?)?

thanks for your time. I am planning to use Janusgraph, but not sure what are the caveats of using it over another database which also implements tinkerpop. I intentionally kept the question open ended, because there is little information(which i could find) about experiences of using tinkerpop based graph, and which ones seems to be working fine. Would like to know what is your experiences of using different types of graph databases.
