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?

sql::translator::schema::index

SQL::Translator::Schema::Index(3pm)			User Contributed Perl Documentation		       SQL::Translator::Schema::Index(3pm)

NAME

       SQL::Translator::Schema::Index - SQL::Translator index object

SYNOPSIS

	 use SQL::Translator::Schema::Index;
	 my $index = SQL::Translator::Schema::Index->new(
	     name   => 'foo',
	     fields => [ id ],
	     type   => 'unique',
	 );

DESCRIPTION

       "SQL::Translator::Schema::Index" is the index object.

       Primary and unique keys are table constraints, not indices.

METHODS

   new
       Object constructor.

	 my $schema = SQL::Translator::Schema::Index->new;

   fields
       Gets and set the fields the index is on.  Accepts a string, list or arrayref; returns an array or array reference.  Will unique the field
       names and keep them in order by the first occurrence of a field name.

	 $index->fields('id');
	 $index->fields('id', 'name');
	 $index->fields( 'id, name' );
	 $index->fields( [ 'id', 'name' ] );
	 $index->fields( qw[ id name ] );

	 my @fields = $index->fields;

   is_valid
       Determine whether the index is valid or not.

	 my $ok = $index->is_valid;

   name
       Get or set the index's name.

	 my $name = $index->name('foo');

   options
       Get or set the index's options (e.g., "using" or "where" for PG).  Returns an array or array reference.

	 my @options = $index->options;

   table
       Get or set the index's table object.

	 my $table = $index->table;

   type
       Get or set the index's type.

	 my $type = $index->type('unique');

       Get or set the index's type.

       Currently there are only four acceptable types: UNIQUE, NORMAL, FULL_TEXT, and SPATIAL. The latter two might be MySQL-specific. While both
       lowercase and uppercase types are acceptable input, this method returns the type in uppercase.

   equals
       Determines if this index is the same as another

	 my $isIdentical = $index1->equals( $index2 );
