Service Support for mongos.exe You may now run mongos.exe instances as a Windows Service. See the mongos.exe reference and Configure a Windows Service for MongoDB (page 30) and SERVER-1589 840 for more information. Log Rotate Command Support MongoDB for Windows now supports log rotation by way of the logRotate database command. See SERVER-2612 841 for more information. New Build Using SlimReadWrite Locks for Windows Concurrency Labeled “2008+” on the Downloads Page$^{842}$, this build for 64-bit versions of Windows Server 2008 R2 and for Windows 7 or newer, offers increased performance over the standard 64-bit Windows build of MongoDB. See SERVER-3844 843 for more information. Index Definitions Handled by mongodump and mongorestore When you specify the --collection option to mongodump , mongodump will now backup the definitions for all indexes that exist on the source database. When you attempt to restore this backup with mongorestore , the target mongod will rebuild all indexes. See SERVER- 808 844 for more information. mongorestore now includes the --noIndexRestore option to provide the preceding behavior. Use --noIndexRestore to prevent mongorestore from building previous indexes. mongooplog for Replaying Oplogs The mongooplog tool makes it possible to pull oplog entries from mongod instance and apply them to another mongod instance. You can use mongooplog to achieve point-in-time backup of a MongoDB data set. See the SERVER-3873 845 case and the mongooplog reference. Authentication Support for mongotop and mongostat mongotop and mongostat now contain support for username/password authentication. See SERVER-3875 846 and SERVER-3871 847 for more information regarding this change. Also consider the documentation of the following options for additional information: Write Concern Support for mongoimport and mongorestore mongoimport now provides an option to halt the import if the operation encounters an error, such as a network interruption, a duplicate key exception, or a write error. The --stopOnError option will produce an error rather than silently continue importing data. See SERVER-3937 848 for more information. In mongorestore , the --w option provides support for configurable write concern. 905 12.2.
