Thanks Dave for the suggestion. I have all my columns name in this
collection-
*final Collection<String> attributeNames*
*
*
And all my results back in this resultset-
*ResultSet result =
CassandraDatastaxConnection.getSession().execute(query);*
*
*
Now I need to store the column name and its corresponding value in the
Below Map-
*Map<String, String> attributes = new
ConcurrentHashMap<String, String>();*
*
*
What's the best way to do that in this case?
Thanks for the help.
