$maxTimeMS

$maxTimeMS

Note

Deprecated in the mongo Shell since v3.2

Starting in v3.2, the $maxTimeMS operator is deprecated in the mongo shell. In the mongo shell, use cursor.maxTimeMS() instead.

New in version 2.6: The $maxTimeMS operator specifies a cumulative time limit in milliseconds for processing operations on the cursor. MongoDB interrupts the operation at the earliest following interrupt point.

The mongo shell provides the cursor.maxTimeMS() method

copy

db.collection.find().maxTimeMS(100)

You can also specify the option in either of the following forms:

copy

db.collection.find( { $query: { }, $maxTimeMS: 100 } )
db.collection.find( { } )._addSpecial("$maxTimeMS", 100)

Interrupted operations return an error message similar to the following:

copy

error: { "$err" : "operation exceeded time limit", "code" : 50 }
