“Updating Netezza with Data from Q Replication”

Posted by Frank Fillmore on January 2, 2013 under DB2 for Linux Unix Windows, DB2 for z/OS, IDAA, InfoSphere, Netezza, Q-Replication.

In cooperation with IBM, The Fillmore Group performed a proof-of-concept for a large, well-known midwestern retailer in 2011 to demonstrate the use of IBM InfoSphere Data Replication (IIDR) Event Publisher (EP) feature to feed OLTP data into a Netezza appliance.  There is now a native changed data capture Apply component for Netezza built on technology IBM acquired from Data Mirror.  This provides for heterogeneous near-real-time OLTP replication to a Netezza appliance.  However – and this is a significant “however” – your shop might already be using Q Replication.  If you are replicating from a DB2 OLTP database, does it make sense to introduce a different replication technology just to keep your Netezza appliance current?

The answer is found in the developerworks post “Updating Netezza with Data from Q Replication“.  Built on the template developed by The Fillmore Group, IBM has published a java consumer that will provide mini-batches of comma delimited data files created by IIDR Event Publisher for ingestion into Netezza using native Netezza utilities.  Note that this approach works for both the new PureData System for Analytics as well as IBM DB2 Analytics Accelerator (IDAA) which are built on Netezza technology.

Kudos to IBMer Cecile Madsen of Silicon Valley Lab for her work on this technique.
