The inMemory storage engine uses document-level locking. For more details, see In-Memory Storage Engine. Other than some metadata, the for-test storage engine does not maintain any on-disk data, removing the need to clean up between test runs. The for-test storage engine is unsupported. The ephemeralForTest storage engine uses collection-level locking.

SpiderMonkey provides support for additional platforms and has an improved memory management model. SpiderMonkey Compatibility Changes. Equivalent to initializing Bulk operations builder, using Bulk methods to add operations, and running Bulk. Equivalent to db. That is, for the WiredTiger storage engine, these operations can guarantee that the data files do not change, ensuring consistency for the purposes of creating backups. For more information, see db. For more information, see explain. For explain operations run in executionStats or allPlansExecution mode, the explain output contains the keysExamined statistic, representing the number of index keys examined during index scans.

Prior to 3. As of 3. The new version improves performance of 2dsphere index queries over smaller regions. In addition, for both 2d indexes and 2dsphere indexes , the performance of geoNear queries has been improved for dense datasets. By default, the mechanism captures data at 1 second intervals. To modify the interval, see diagnosticDataCollectionPeriodMillis. MongoDB creates a diagnostic. The diagnostic data is stored in files under this directory. The maximum size of the diagnostic files is configurable with the diagnosticDataCollectionFileSizeMB , and the maximum size of the diagnostic.

The default values for the capture interval and the maximum sizes are chosen to provide useful data to MongoDB engineers with minimal impact on performance and storage size. Typically, these values will only need modifications as requested by MongoDB engineers for specific diagnostic purposes. See --journalCommitInterval option. In previous versions, the option is applicable to MMAPv1 storage engine only. For the corresponding configuration file setting, MongoDB 3.

The deprecated storage. After successful execution of command , it will show logging info in standard console itself as shown follows. If you specify the logpath option, then logging will direct to that log file instead of showing up on standard console.

Starting with the last config server listed in the configDB setting:. Start the 3.

If using a configuration file , specify sharding. Repeat for the config server listed second in the configDB setting, and finally the config server listed first in the configDB setting.

Replace each mongos instance with the 3. Re-enable the balancer as described in Enable the Balancer. Once the sharded cluster binaries have been upgraded to 3. Version 5. Download 3. Replace with 3. Upgrade secondary members of the replica set. To check the member's state, issue rs.

Step down the replica set primary. Upgrade the primary. Disable the Balancer.
