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?

LEARN ABOUT PHP

array_column

ARRAY_COLUMN(3) 							 1							   ARRAY_COLUMN(3)

array_column - Return the values from a single column in the input array

SYNOPSIS

       array array_column (array  $array, mixed  $column_key, [mixed  $index_key = null])

DESCRIPTION

       array_column(3)	returns  the  values  from  a  single  column of the $array, identified by the $column_key. Optionally, you may provide an
       $index_key to index the values in the returned array by the values from the $index_key column in the input array.

PARAMETERS

	      o $array
		- A multi-dimensional array (record set) from which to pull a column of values.

	      o $column_key
		- The column of values to return. This value may be the integer key of the column you wish to retrieve, or it may  be  the  string
		key  name  for an associative array. It may also be NULL to return complete arrays (useful together with $index_key to reindex the
		array).

	      o $index_key
		- The column to use as the index/keys for the returned array. This value may be the integer key of the column, or it  may  be  the
		string key name.

RETURN VALUES

	Returns an array of values representing a single column from the input array.

EXAMPLES

       Example #1

	      Get column of first names from recordset

	      <?php
	      // Array representing a possible record set returned from a database
	      $records = array(
		  array(
		      'id' => 2135,
		      'first_name' => 'John',
		      'last_name' => 'Doe',
		  ),
		  array(
		      'id' => 3245,
		      'first_name' => 'Sally',
		      'last_name' => 'Smith',
		  ),
		  array(
		      'id' => 5342,
		      'first_name' => 'Jane',
		      'last_name' => 'Jones',
		  ),
		  array(
		      'id' => 5623,
		      'first_name' => 'Peter',
		      'last_name' => 'Doe',
		  )
	      );

	      $first_names = array_column($records, 'first_name');
	      print_r($first_names);
	      ?>

	      The above example will output:

	      Array
	      (
		  [0] => John
		  [1] => Sally
		  [2] => Jane
		  [3] => Peter
	      )

       Example #2

	       Get column of last names from recordset, indexed by the "id" column

	      <?php
	      // Using the $records array from Example #1
	      $last_names = array_column($records, 'last_name', 'id');
	      print_r($last_names);
	      ?>

	      The above example will output:

	      Array
	      (
		  [2135] => Doe
		  [3245] => Smith
		  [5342] => Jones
		  [5623] => Doe
	      )
