This is the Problem:
I'm building a Large DataMart with a big
table and I want to improve the performace using aggregates I mean a set of
table that store some specific aggregacion of the main table, like materialized
views, I know that this feature is not implemented yet in postgres, And I see a
interesting article to implementing this using a set of triggers, but I thing
the big problem is not the rate of the updates or the real time consistence
between both table, the main and the agregates. I thing the really problem is
how to let it know to the RDMS engine that this aggregates exist!, I mean
when I run a query I want to the Database engine run the query against the
correct table.
I thing if some day postgres allow to do this, will
could use postgres more confortablement in Data warehouse proyect.
I read today the TODO list of postgres and I
don't see anithing like this...
Any alternative??
or how you solve the problem of the agregates in
yours DataMarts???
any commentari is well recived
