Do you know of a RFE regarding the MQT Refresh Immediate
or better, Is IBM going to add this DB feature anytime soon ?

Doubtful...

Last I heard, while MQTs are thought to be useful for summary data...
on the i, an EVI indexes with calculated summary columns is usually a
better choice.


We use an MQT for a very large join that takes too long to
materialize at execution time. And since it currently requires an
exclusive lock, it is a pain that we can only refresh this MQT at 3am.
