Greenplum, MapReduce, and Hadoop
If your job involves processing massive amounts of data you should familiarize yourself with Greenplum, MapReduce, and Hadoop.
Both Greenplum and Hadoop make use of the MapReduce framework pioneered by Google.
You can run Hadoop on Amazon Elastic MapReduce to play around with the technology.
There have also been two Hadoop books published recently. I have ordered both of them and can’t wait to hold them in my hands.
No books on Greenplum, but they have some good whitepapers on their website.
