I know how to ping in Perl. That is easy. What I am wondering is if there is a way for Perl to determine whether the ping was successful or not. Or do I need to save the results out and parse the results seperately looking for the #of tries and successful revieves.
Thanks. (1 Reply)

MONGOCOLLECTION.PARALLELCOLLECTIONSCAN(3) 1 MONGOCOLLECTION.PARALLELCOLLECTIONSCAN(3)
MongoCollection::parallelCollectionScan - Returns an array of cursors to iterator over a full collection in parallel
SYNOPSIS
public array[MongoCommandCursor] MongoCollection::parallelCollectionScan (int $num_cursors)
DESCRIPTION
This method returns an array of a maximum of num_cursors cursors. An iteration over one of the returned cursors results in a partial set
of documents for a collection. Iteration over all the returned cursors results in getting every document back from the collection.
This method is a wrapper for the parallelCollectionScan MongoDB command.
PARAMETERS
o $num_cursors
- The number of cursors to request from the server. Please note, that the server can return less cursors than you requested.
RETURN VALUES
Returns an array of MongoCommandCursor objects.
EXAMPLES
Example #1
MongoCollection.parallelCollectionScan(3) example
Returning all documents in a collection by using multiple cursors.
<?php
$m = new MongoClient;
$c = $m->demo->cities;
/* Request three cursors */
$cursors = $c->parallelCollectionScan( 3 );
/* Add all the cursors to the MultipleIterator */
$mi = new MultipleIterator( MultipleIterator::MIT_NEED_ANY );
foreach ( $cursors as $cursor )
{
$mi->attachIterator( $cursor );
}
/* Iterate over all the associated cursors */
foreach ( $mi as $items )
{
foreach ( $items as $item )
{
if ( $item !== NULL )
{
echo $item['name'], "
";
}
}
}
?>
