$maxTimeMS¶
- $maxTimeMS¶
2.6 新版功能: 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
db.collection.find().maxTimeMS(100)
You can also specify the option in either of the following forms:
db.collection.find( $query: { } , $maxTimeMS: 100 } ) db.collection.find()._addSpecial("$maxTimeMS", 100)
Interrupted operations return an error message similar to the following:
error: { "$err" : "operation exceeded time limit", "code" : 50 }
