That clearly mentions OLTP ... Whatever :) Let's make it clear: I need to run aggregates/roll ups/drill downs on large dataset (100m+) but the query should return result (less than 1000 rows, mostly around 100) under 30 sec My point is that MPP (same box used) solution can deliver required performance in most cases (>75%). -- Ondrej Ivanic (ondrej.ivanic@xxxxxxxxx) -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
