Index server

Hi guys,

I have postgresql server with huge amount of data, nearly 2 billion records. each record is at most 50 bytes(4 integer fields). I need to build index on all column to do fast reporting. but indexes becomes bloat after some time. almost 80% of database size is because of its huge indexes. I need some comprehensive external indexing solution so I remove indexes on DB. I found Lucene but it is for full text searching. my fields are all integer. Is there any good solution?

TM::Index::Reified(3pm) 				User Contributed Perl Documentation				   TM::Index::Reified(3pm)

NAME
TM::Index::Reified - Topic Maps, Indexing support (reification axis) SYNOPSIS
# somehow get a map (any subclass of TM will do) my $tm = ... # one option: create an eager index (immediate population) use TM::Index::Reified; my $idx = new TM::Index::Reified ($tm, closed => 1); # for most operations which involve is_reified to be called # should be much faster DESCRIPTION
This index can be attached to a map if the method "is_reified" is about to be called very often. Most likely you will want to have the index to be closed, i.e. populated. The package inherits most of its functionality from TM::Index. NOTE: As for all indices, modifications of the underlying map are not reflected automatically. INTERFACE
Constructor The constructor/destructor is inherited from TM::Index. Methods attach, detach This index attaches in a special way to the map. populate Invoking this, you will fill this index with authoritative information. SEE ALSO
