Every one of the Anker 's good ideas comes mired in caveats, and all the user tweaking in the world can't solve its fundamental design problems. The software deserves praise for making macros so easy to record and use, but otherwise, the feature set is pretty standard. Whereas, the range of 16 million colors empowers you to set your desired lighting color as profile indicator, that further embellishes the look of the device. Latest: smalltech 10 minutes ago.

Before refining the shard key, ensure that all or most documents in the collection have the suffix fields, if possible, to avoid having to populate the field afterwards. In earlier versions, once you select a shard key, you cannot modify the shard key. With the ability to refine a shard key with a suffix, it may be that not all documents in the collection have the suffix fields. In earlier versions, shard key fields must exist in every document for a sharded collection.
For details, see Missing Shard Key Fields. To minimize latencies, mongos instances, by default, can use hedge reads. With hedged reads, the mongos instances can route read operations to multiple members per each queried shard and return results from the first respondent per shard. By default, mongos instances support using hedged reads. To turn off a mongos instance's support for hedged reads, set the readHedgingMode parameter for the mongos.
Hedged reads are specified per operation as part of the read preference. Non- primary read preferences support hedged reads. Read preference nearest specifies hedged read by default. Hedged Reads. Read Preference for Sharded Clusters. To specify hedged read for a read preference, MongoDB 4. The following mongo shell methods can accept hedge options to enable hedged read for the specified read preference:.
With the command, users can verify that initial chunk creation and migration has finished. This behavior results in faster servicing of initial client connections after a mongos instance is started or restarted. In particular, this allows sites that employ multiple mongos instances to restart them as necessary, or add new ones, without initial client requests to those instances needing to wait on connection establishment.
Both routing table preloading and connection pool prewarming are enabled by default. Default : true Enabled. Enables or disables support for preloading the routing table on startup for the mongos. Enables or disables support for prewarming the connection pool on startup for the mongos. Default : 2 seconds. Sets the timeout in milliseconds before client connections to the mongos are allowed regardless of established connection pool size. Running flushRouterConfig is no longer required after executing the movePrimary or dropDatabase commands.
These two commands now automatically refresh a sharded cluster's routing table as needed when run. Manually issuing the flushRouterConfig command is still recommended in the cases described under flushRouterConfig Considerations. Prior to 4. Compound hashed sharding supports features like zone sharding , where the prefix i. For example, the following operation shards a collection on a compound hashed shard key that supports zoned sharding:.
Compound hashed sharding also supports shard keys with a hashed prefix for resolving data distribution issues related to monotonically increasing fields For example, the following operation shards a collection on a compound hashed shard key where the hashed field is the shard key prefix:. Hashed Sharding. Compound Hashed Indexes.
Chunk ranges awaiting cleanup after a chunk migration are now persisted in the config. In the event of a failover, the shard's new primary reads the documents in the config.
The document that describes a range awaiting cleanup is deleted from the config. The cleanupOrphaned command no longer deletes orphaned documents from a shard. Instead, cleanupOrphaned waits for orphaned documents that are scheduled for deletion from a shard to be deleted. Set the disableResumableRangeDeleter parameter to true on a shard's primary to pause range deletion on the shard.
The command serverStatus returns the field shardedIndexConsistency to report on index inconsistencies when run on the config server primary. To configure the index consistency checks, MongoDB provides the following parameters:. In earlier versions, removeShard returns an error if another removeShard operation is in progress. For MongoDB 4. For chunks that are too large to migrate , starting in MongoDB 4.
A new balancer setting attemptToBalanceJumboChunks allows the balancer to migrate chunks too large to move as long as the chunks are not labeled jumbo. The moveChunk command can specify a new option forceJumbo to allow for the migration of chunks that are too large to move. The chunks may or may not be labeled jumbo. The find and findAndModify projection can accept aggregation expressions and aggregation syntax, including the use of literals and aggregation variables. With the use of aggregation expressions and syntax, you can project new fields or project existing fields with new values.
The find and findAndModify projection can specify embedded fields using the nested form; e. In earlier versions, you can only use the dot notation. Path Collision Restrictions. The indexKey metadata is for debugging purposes only and not for application logic.
You can sort the resulting documents by their search relevance, i. You can implicitly create a collection , such as with:. You can explicitly create a collection using the create command or its helper db. The db. When creating an index inside a transaction:. You can create an index on a non-existing collection. The collection is created as part of the operation. You can create an index on a new empty collection created earlier in the same transaction.
When setting the parameter for a sharded cluster, set the parameter on all shards. For explicit creation of a collection or an index inside a transaction, the transaction read concern level must be "local". Explicit creation is through:. Transactions and Operations. With this change, queries which perform a sort on fields that contain duplicate values are much more likely to result in inconsistent sort orders for those values.
To guarantee sort consistency when using sort on duplicate values, include an additional field in your sort that contains exclusively unique values. See Sort Consistency for more information. MongoDB Enterprise 4. When run, mongokerberos returns a report indicating any issues encountered, and provides potential advice for resolving them.
In versions 4. OCSP stapling. OCSP must-staple extension. You can set these parameters at startup using the setParameter configuration file setting or the --setParameter command line option:.
Specifically, the following connections to a mongod or mongos can trigger x. A mongod cluster member performing x. A mongos cluster member performing x. Consider proactively renewing client x. Set the parameter to 0 to disable the warning. A mongod , mongos , or mongoldap returns an error if one of the user to Distinguished Name DN mappings cannot be evaluated due to networking or authentication failures to the LDAP server. The mongod , mongos , or mongoldap rejects the connection request and does not check the remaining mappings, if any.
Log entries are written as a series of key-value pairs, where each key indicates a log message field type, such as "severity", and each corresponding value records the associated logging information for that field type, such as "informational".
This includes log output sent to the file , syslog , and stdout standard out log destinations , as well as the output of the getLog command.
The following log messages in JSON format indicate that a mongod is listening and ready for connections:. Structured logging with key-value pairs allows for efficient log analysis by automated tools or log ingestion services, and makes programmatic log parsing easier and more powerful. When working with MongoDB structured logging, the third-party jq command-line utility is a useful tool that allows for easy pretty-printing of log entries, and powerful key-based matching and filtering.
For more information on structured logging, including a detailed examination of log entry components as well as command-line parsing examples, see Log Messages. If set to an array, each password is tried until one succeeds.
SLES 15 on the sx architecture. Ubuntu Authenticating in this manner uses the new MONGODB-AWS authentication mechanism , and requires that you provide an AWS access key ID and a secret access key, which may be specified in the connection string or on the command-line via the --username and --password options. Alternatively, if the AWS access key ID, secret access key, or session token are defined on your platform using their respective AWS IAM environment variables the mongo shell will use these environment variable values to authenticate; you do not need to specify them in the connection string.
For documentation on previous versions of the listed tools, reference that version of the MongoDB server manual. MongoDB 3. See the mongokerberos reference page for more information. Projects in mongodb-labs are experimental and not officially supported by MongoDB. If you were relying on the MongoDB 4. The official MongoDB Rust driver is now available.
The official MongoDB Swift driver is now available. Compound hashed indexes require featureCompatibilityVersion set to 4. Compound Hashed Shard Keys. An index hidden from the query planner is not evaluated as part of query plan selection. By hiding an index from the planner, users can evaluate the potential impact of dropping an index without having to drop the index.
If the impact is negative, the user can unhide the index instead of having to recreate a dropped index. And because indexes are fully maintained while hidden, hidden indexes are immediately available for use once unhidden. For details, see Hidden Indexes. To support hidden indexes , MongoDB introduces:.
A new index option hidden. The option can be specified in the following operations:. New mongo shell helper methods to hide or unhide existing indexes:. If an index specified to dropIndexes is still building, dropIndexes attempts to abort the in-progress build.
Aborting an index build has the same effect as dropping the built index. This behavior also applies to the shell helpers db. The index specified to dropIndex must be the only index associated to the index builder, i.
To drop a specific index out of a set of related in-progress builds, wait until the index builds complete and specify that index to dropIndexes or its shell helpers.
For replica sets or shard replica sets, aborting an index on the primary does not simultaneously abort secondary index builds. MongoDB attempts to abort the in-progress builds for the specified indexes on the primary and if successful creates an associated abort oplog entry. Secondary members with replicated in-progress builds wait for a commit or abort oplog entry from the primary before either committing or aborting the index build.
Index Builds on Populated Collections. MongoDB removes the following command s and mongo shell helper s :. Use mongoexport and mongoimport , or.
Use the mongo shell helper method PlanCache. Available starting in version 4. Linux operating systems running Linux Kernel 3. Linux operating systems running Linux Kernel 4. Set to 1 to enable only outbound TFO connections. Set to 2 to enable only inbound TFO connections. Set to 3 to enable inbound and outbound TFO connections. A complete discussion of TFO is outside the scope of this documentation.
For more information on TFO, start with the following external resources:. TCP Fast Open en. If MongoDB cannot use an index or indexes to obtain the sort order for a given cursor. A blocking sort indicates that MongoDB must consume and process all input documents to the sort before returning results. Blocking sorts do not block concurrent operations on the collection or database.
For blocking sort operations which require more than megabytes of system memory, MongoDB returns an error unless the query specifies cursor. For more information on sorting and index use, see Sort and Index Use. Memory Limits on Sort Operations. With allowDiskUse: true , the operation can use temporary files on disk when processing a non-indexed "blocking" sort operation that exceeds the megabyte memory limit. For the db.
Memory Limits On Sort Operations. Sort and Index Use. For featureCompatibilityVersion set to "4. For a collection or a view, the namespace includes the database name, the dot.
The log messages for validate operations include dataThroughputAverage and dataThroughputLastSecond information.
Previously, compact blocked all operations for the database it was operating on, including MongoDB CRUD Operations , and was therefore only appropriate for use during scheduled maintenance periods. Previously, the force option, when set to true enabled compact to run on the primary in a replica set and if set to false , returned an error when run on a primary.
Collections with inconsistencies between the collection data and one or more indexes. In earlier versions of MongoDB, the mongod --repair option rebuilt all indexes for all collections.
The relevant find, insert, update, delete or aggregate metric will be incremented with each operation on a cluster. When the mongod and mongos processes receive a SIGUSR2 signal, backtrace details are added to the logs for each process thread. Backtrace details show the function calls for the process, which can be used for diagnostics and provided to MongoDB Support if required.
For more information, see Generate a Backtrace. Previously, a warning would only be logged if this value was under See Recommended ulimit Settings for more information. The replanReason field contains the reason the query system evicted a cached plan.
The dbStats command and its mongo shell helper db. The collStats command, its mongo shell helper db. The delete command and the associated mongo shell methods db. The findAndModify command and the associated mongo shell methods:. To disable JavaScript execution on a mongos instance:.
Set security. Specify the --noscripting command-line option. Clients which do not explicitly specify a given read or write concern setting inherit the corresponding global default setting.
For replica sets, issue the command against the primary member. For sharded clusters, issue the command from a mongos. The following table shows the possible read concern provenance values and their significance:. If a read operation is logged or profiled, the operation entry contains the read concern object, including the provenance field. MongoDB does not recommended specifying the provenance field in requests to the server.
This field should only be used for diagnostic purposes. The following table shows the possible write concern provenance values and their significance:.
If a write operation is logged or profiled, the operation entry contains the write concern object, including the provenance field. The currentOp command includes dataThroughputAverage and dataThroughputLastSecond information when reporting on validate operations in progress. To control the number of times the mongod retries a failed initial connection to the KMIP server:.
