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?

px_get_info

PX_GET_INFO(3)															    PX_GET_INFO(3)

px_get_info - Return lots of information about a paradox file

SYNOPSIS

       array px_get_info (resource  $pxdoc)

DESCRIPTION

PARAMETERS

	      o $pxdoc
		- Resource identifier of the paradox database as returned by px_new(3).

RETURN VALUES

	Returns an associated array with lots of information about a paradox file. This array is likely to be extended in the future.

	      o fileversion
		-Version of file multiplied by 10, e.g. 70.

	      o tablename
		-Name  of  table  as  stored in the file. If the database was created by pxlib, then this will be the name of the file without the
		extension.

	      o numrecords
		-Number of records in this table.

	      o numfields
		-Number of fields in this table.

	      o headersize
		-Number of bytes used for the header. This is usually 0x800.

	      o recordsize
		-Number of bytes used for each record. This is the sum of all field sizes (available since version 1.4.2).

	      o maxtablesize
		- This value multiplied by 0x400 is the size of a data block in bytes. The maximum number of records in a datablock is the integer
		part of (maxtablesize * 0x400 - 8) / recordsize.

	      o numdatablocks
		- The number of data blocks in the file. Each data block contains a certain number of records which depends on the record size and
		the data block size (maxtablesize). Data blocks may not necessarily be completely filled.

	      o numindexfields
		- Number of fields used for the primary index. The fields do always start with field number 1.

	      o codepage
		- The DOS codepage which was used for encoding fields with character data. If the target encoding is not set with px_set_targeten-
		coding(3)   this  will	be  the  encoding  for	character  fields  when  records  are  being  accessed	with  px_get_record(3)	or
		px_retrieve_record(3).
