public class MongoClientURI extends Object
The format of the URI is:
mongodb://is a required prefix to identify that this is a string in the standard connection format.
username:password@are optional. If given, the driver will attempt to login to a database after connecting to a database server. For some authentication mechanisms, only the username is specified and the password is not, in which case the ":" after the username is left off as well
host1is the only required part of the URI. It identifies a server address to connect to.
:portXis optional and defaults to :27017 if not provided.
/databaseis the name of the database to login to and thus is only relevant if the
username:password@syntax is used. If not specified the "admin" database will be used by default.
?optionsare connection options. Note that if
databaseis absent there is still a
/required between the last host and the
?introducing the options. Options are name=value pairs and the pairs are separated by "&". For backwards compatibility, ";" is accepted as a separator in addition to "&", but should be considered as deprecated.
The following options are supported (case insensitive):
Server Selection Configuration:
serverSelectionTimeoutMS=ms: How long the driver will wait for server selection to succeed before throwing an exception.
localThresholdMS=ms: When choosing among multiple MongoDB servers to send a request, the driver will only send that request to a server whose ping time is less than or equal to the server with the fastest ping time plus the local threshold.
Server Monitoring Configuration:
heartbeatFrequencyMS=ms: The frequency that the driver will attempt to determine the current state of each server in the cluster.
Replica set configuration:
replicaSet=name: Implies that the hosts given are a seed list, and the driver will attempt to find all members of the set.
ssl=true|false: Whether to connect using SSL.
sslInvalidHostNameAllowed=true|false: Whether to allow invalid host names for SSL connections.
connectTimeoutMS=ms: How long a connection can take to be opened before timing out.
socketTimeoutMS=ms: How long a send or receive on a socket can take before timing out.
Connection pool configuration:
maxPoolSize=n: The maximum number of connections in the connection pool.
waitQueueMultiple=n: this multiplier, multiplied with the maxPoolSize setting, gives the maximum number of threads that may be waiting for a connection to become available from the pool. All further threads will get an exception right away.
waitQueueTimeoutMS=ms: The maximum wait time in milliseconds that a thread may wait for a connection to become available.
Write concern configuration:
true: the driver ensures that all writes are acknowledged by the MongoDB server, or else throws an exception. (see also
false: the driver does not ensure that all writes are acknowledged by the MongoDB server.
true: the driver waits for the server to group commit to the journal file on disk.
false: the driver does not wait for the server to group commit to the journal file on disk.
Read preference configuration:
slaveOk=true|false: Whether a driver connected to a replica set will send reads to slaves/secondaries.
readPreference=enum: The read preference for this connection. If set, it overrides any slaveOk value.
readPreferenceTags=string. A representation of a tag set as a comma-separated list of colon-separated key-value pairs, e.g.
"dc:ny,rack:1". Spaces are stripped from beginning and end of all keys and values. To specify a list of tag sets, using multiple readPreferenceTags, e.g.
maxStalenessSeconds=seconds. The maximum staleness in seconds. For use with any non-primary read preference, the driver estimates the staleness of each secondary, based on lastWriteDate values provided in server isMaster responses, and selects only those secondaries whose staleness is less than or equal to maxStalenessSeconds. Not providing the parameter or explicitly setting it to -1 indicates that there should be no max staleness check. The maximum staleness feature is designed to prevent badly-lagging servers from being selected. The staleness estimate is imprecise and shouldn't be used to try to select "up-to-date" secondaries. The minimum value is either 90 seconds, or the heartbeat frequency plus 10 seconds, whichever is greatest.
authMechanism=MONGO-CR|GSSAPI|PLAIN|MONGODB-X509: The authentication mechanism to use if a credential was supplied. The default is unspecified, in which case the client will pick the most secure mechanism available based on the sever version. For the GSSAPI and MONGODB-X509 mechanisms, no password is accepted, only the username.
authSource=string: The source of the authentication credentials. This is typically the database that the credentials have been created. The value defaults to the database specified in the path portion of the URI. If the database is specified in neither place, the default value is "admin". This option is only respected when using the MONGO-CR mechanism (the default).
gssapiServiceName=string: This option only applies to the GSSAPI mechanism and is used to alter the service name..
Server Handshake configuration:
appName=string: Sets the logical name of the application. The application name may be used by the client to identify the application to the server, for use in server logs, slow query logs, and profile collection.
Note: This class is a replacement for
MongoURI, to be used with
MongoClient. The main difference in
behavior is that the default write concern is
