I assume people on both sides of data warehouses (users and providers) are asking the same question. IBM Netezza and Cloudera seem to agree on the answer:
IBM Netezza had worked with Cloudera to put together a compelling demo to highlight the value of our combined solution of CDH/Hadoop and Netezza. Through an interesting use case, the demo showed how businesses could have their “hot” data (most recent data) residing in Netezza, “warm” data (longer time range data) residing in HDFS, while leveraging the Cloudera Connector for Netezza and Oozie (workflow engine part of CDH) to provide deeper insights to business executives.
I would have liked to know more details about the use case though. Just categorizing data in “hot” and “warm” is not enough to understand the advantages of each piece.
