Thanks DuyHai for revert.
There are going to be pauses between fetching pages. For that they do seem
to have an option to save page state. I will try that out.

Thank you Indra for your suggestion.
But the thing is apart from pulling data based on supercol in the below

rowkey.If I change the model as u mentioned this query becomes slow.
I need to do both the retrievals efficiently.

Hello Torsten,
I am working on Cassandra for last 4 weeks and am trying to
load large amount of data.Data is in a csv file.I am trying to use the Bulk
loading technique but am not clear with the process.Could you please explain
the process for the bulk load?
Thanks,
Priyanka
Thanks a lot Sebastien.
Did you use hadoop map reduce or bulk loading techniques for loading data?
regards,
Priyanka
