  • What do you need to do with those 650.000 items? I suppose your are not showing all that items in the resulting page. If you explain why do you need them is easier to solve your problem. – sanzante Nov 5 '15 at 7:34
  • I have a Content Type for Village Data Where store particular State->District->Block->Village Data. I want to show records based on filters. I have a Role Village Auditor that check data by state and village auditor want to check how many Village Entries in particular State. – Kamal Oberoi Nov 5 '15 at 7:42
  • This doesn't explain whay you need to load all Villages at the same time. Why don't you use Views? – sanzante Nov 7 '15 at 13:34

You can fetch all child at any level by using this code :

function taxonomy_get_children_all($tid, $vid = 0, $key = 'tid'){
  $c = taxonomy_get_children($tid, $vid, $key);
  $result = array();
  foreach ($c as $t => $d){
    $result[$t] = $d;
    $below = taxonomy_get_children_all($t, $vid, $key);
    if (!empty($below)) {
      $result[$t]->children = array();
      foreach ($below as $nt => $nd){
        $result[$t]->children[$nt] = $nd;
      }
    }
  }
  return $result;
}

OR

You can do it by adding custom database query using function function taxonomy_get_children
