(defn ^com.mongodb.CommandResult command
"Runs a database command (please check MongoDB documentation for the complete list of commands). Some common commands
are:
"Runs a database command (please check MongoDB documentation for the complete list of commands).
{ :buildinfo 1 } returns version number and build information about the current MongoDB server, should be executed via admin DB.
Ordering of keys in the command document may matter. Please use sorted maps instead of map literals, for example:
(sorted-map geoNear \"bars\" :near 50 :test 430 :num 10)
{ :collstats collection-name [ :scale scale ] } returns stats about given collection.
{ :dbStats 1 } returns the stats of current database
{ :dropDatabase 1 } deletes the current database
{ :findAndModify find-and-modify-config } runs find, modify and return for the given query.
Takes :query, :sory, :remove, :update, :new, :fields and :upsert arguments.
Please refer MongoDB documentation for details. http://www.mongodb.org/display/DOCS/findAndModify+Command
{ :fsync config } performs a full fsync, that flushes all pending writes to database, provides an optional write lock that will make
backups easier.
Please refer MongoDB documentation for details :http://www.mongodb.org/display/DOCS/fsync+Command
{ :getLastError 1 } returns the status of the last operation on current connection.
{ :group group-config } performs grouping aggregation, docs and support for grouping are TBD in Monger.
{ :listCommands 1 } displays the list of available commands.
{ :profile new-profile-level } sets the database profiler to profile level N.
{ :reIndex coll } performs re-index on a given collection.
{ :renameCollection old-name :to new-name } renames collection from old-name to new-name
{ :repairDatabase 1 } repair and compact the current database (may be very time-consuming, depending on DB size)
Replica set commands
{ :isMaster 1 } checks if this server is a master server.
{ :replSetGetStatus 1 } get the status of a replica set.
{ :replSetInitiate replica-config } initiate a replica set with given config.
{ :replSetReconfig replica-config } set a given config for replica set.
{ :replSetStepDown seconds } manually tell a member to step down as primary. It will become primary again after specified amount of seconds.
{ :replSetFreeze seconds } freeze state of member, call with 0 to unfreeze.
{ :resync 1 } start a full resync of a replica slave
For more information, please refer Mongodb Replica Set Command guide: http://www.mongodb.org/display/DOCS/Replica+Set+Commands
{ :serverStatus 1 } gets administrative statistics about the server.
{ :shutdown 1 } shuts the MongoDB server down.
{ :top 1 } get a breakdown of usage by collection.
{ :validate namespace-name } validate the namespace (collection or index). May be very time-consuming, depending on DB size.
For :distinct, :count, :drop, :dropIndexes, :mapReduce we suggest to use monger/collection #distinct, #count, #drop, #dropIndexes, :mapReduce respectively.
"
For commonly used commands (distinct, count, map/reduce, etc), use monger/command and monger/collection functions such as
/distinct, /count, /drop, /dropIndexes, and /mapReduce respectively."
