Hi all, We are going to design and develop an asset database for Metron. For this purpose, I have been thinking of a graph schema model to map assets as Nodes and provide relations as Edges. This can be extended to event level to have a particular relation to assets as well as an event to event relation. Regarding technology, I was thinking of using Titan Graph Database (probably JanusGraph) and using HBase and Elasticsearch/Solr as backends. However, there might be a performance issue regarding this decision if we want to use lots of Composite Indices. The problem we will be facing would be the fact that Titan creates separate column family for each Composite Index which HBase is not very good for it. Basically, it would be better to use Cassandra for this purpose.
I would like to understand what work have been done already regarding this problem and what the roadmap will be, so I can make sure we will follow the same strategy. Regards, Ali
