hi,
   i m trying to use cassandra as main data-store and elasticsearch for realtime quries. my question is how do i get the updated data in cassandra for last 1 hour or so to be indexed in elasticsearch.
   once i get the updated data from cassandra i can index that to ES. 
   is there any specific data model i have to follow to get the recent updates of any CF.
    
   thanks subhankar
