PHP Manual :: MongoCursor::maxTimeMS



MongoCursor::limit || MongoCursor::next || MongoCursor || PHP Manual

(PECL mongo >=1.5.0)

MongoCursor::maxTimeMSSets a server-side timeout for this query

Description

public MongoCursor MongoCursor::maxTimeMS ( int $ms )

Specifies a cumulative time limit in milliseconds to be allowed by the server for processing operations on the cursor.

Parameters

ms

Specifies a cumulative time limit in milliseconds to be allowed by the server for processing operations on the cursor.

Return Values

This cursor.

Errors/Exceptions

Throws MongoCursorException if this cursor has started iterating.

Causes methods that fetch results to throw a MongoExecutionTimeoutException if the query takes longer than the specified number of milliseconds in processing time.

Examples

Example #1 MongoCursor::maxTimeMS() example

In the following example, the server will abort the query if the cursor requires more than two seconds in processing time to return its results.

<?php

$cursor 
$collection->find();
$cursor->maxTimeMS(2000);

try {
    
$results iterator_to_array($cursor);
} catch (
MongoExecutionTimeoutException $e) {
    echo 
"query took too long!";
}

?>

Notes

Warning

Unlike MongoCursor::timeout(), which specifies a client-side timeout, MongoCursor::maxTimeMS() can be used to cause the MongoDB server to abort long-running queries. This timeout is cumulative for the lifetime of the cursor (i.e. each batch will contribute to this time limit). The timeout only considers processing time; idle time is not considered.
