Hi All,

We are using Janus graph 0.5.2 with Cassandra as storage and Elastic as search engine. We have 700M + nodes.
Nodes are already connected by edges.

We got a use case to add one more node for each group of connected nodes and then create edges between newly created node and exiting nodes. 
For ex, say

node A and B are connected by an edge.
node C , D and E are connected by an edge.

then,
create one node for A and B and creates edges between newly created node and existing nodes
create one node for C, D and E and creates edges between newly created node and existing nodes

I would appreciate to have suggestions to achieve this considering our huge graph size.

Thanks in advance.

Regards,
Anjani
