my question is how do i get the updated data in cassandra for last 1 hour or so to be indexed in elasticsearch.You cannot.
The best approach is to update elastic search at the same time you update cassandra.

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.
