Maybe you could integrate with Hadoop.

Hi Guys,
Thanks for sharing your experiences and valuable links these are really
helpful.
But I want to do ETL and then wanted to load data in Cassandra. I have link

database which is Netezza. How can I do this in Cas

think about what you wanna get out of your persistent storage and afterwards
think about how to migrate and most of the time how to denor
