How to see the stored data of Cassandra db for janusgraph database by cqlsh

I am new to janusgraph as well as to janusgraph. Now I am able to connect janusgraph with cassandra as backend storage and solr and index storage Currently I am starting gremlin server by the command - sh gremlin-server.sh /conf/gremlin-server/gremlin-server-cql-solr.yaml and connecting it through by sh gremlin.sh.

I have a couple of doubts like - graph.addVertex("name", "Arpan") by using this i am adding the vertice. Now I found that the vertice and edge information is getting stored in the table name
< Keyspacename>.edgestore and I am sure that data is getting inserted to cassandra db becuase g.V().values('name') is showing me the value of vertice name. I am using cqlsh to see the Cassandra data but when I typed the cmd select * from keyspacename.edgestore; Instead of showing text values like - name Arpan its showing data in numeric form like -

            key                | column1            | value

--------------------+--------------------+-----------------------------------------------------------------
0x5800000000000080 | 0x02 | 0x0001048b
0x5800000000000080 | 0x5019a0 | 0xa06a656e6ef9088b
0x5800000000000080 | 0x504ba0 | 0xa0686f6de50c8b011780a03836372d353330b9

How I can see the actual data? And should I use this default table schema or should I create my own?

JanusGraph uses its own data format in the storage layer. It builds the JanusGraph keyspaces and tables in the way that it needs them to be. Therefore, you should definitely not create your own.

You will not be able to read the actual data from cqlsh. To read the data, you'll have the best luck with the Gremlin console, build an app using the (Java?) JanusGraph libraries, or with a visualizer.
