    • getConnectionsPerHost

      public int getConnectionsPerHost()

      The maximum number of connections allowed per host for this MongoClient instance. Those connections will be kept in a pool when idle. Once the pool is exhausted, any operation requiring a connection will block waiting for an available connection.

      Default is 100.

    • getMinConnectionsPerHost

      public int getMinConnectionsPerHost()

      The minimum number of connections per host for this MongoClient instance. Those connections will be kept in a pool when idle, and the pool will ensure over time that it contains at least this minimum number.

      Default is 0.

      Returns:
      the minimum size of the connection pool per host

    • getServerSelectionTimeout

      public int getServerSelectionTimeout()

      Gets the server selection timeout in milliseconds, which defines how long the driver will wait for server selection to succeed before throwing an exception.

      Default is 30,000 milliseconds. A value of 0 means that it will timeout immediately if no server is available. A negative value means to wait indefinitely.

      Returns:
      the server selection timeout in milliseconds.

    • getMaxWaitTime

      public int getMaxWaitTime()

      The maximum wait time in milliseconds that a thread may wait for a connection to become available.

      Default is 120,000 milliseconds. A value of 0 means that it will not wait. A negative value means to wait indefinitely.

      Returns:
      the maximum wait time.

    • getMaxConnectionIdleTime

      Default is 0, indicating no limit to the idle time.

      Returns:
      the maximum idle time, in milliseconds
      Since:
      2.12

    • getMaxConnectionLifeTime

      public int getMaxConnectionLifeTime()

      Default is 0, indicating no limit to the life time.

      Returns:
      the maximum life time, in milliseconds
      Since:
      2.12

    • getMaxConnecting

    • getHeartbeatFrequency

      public int getHeartbeatFrequency()

      Since:
      2.12

    • getMinHeartbeatFrequency

      Default is 500 milliseconds.

      Returns:
      the minimum heartbeat frequency, in milliseconds
      Since:
      2.13

      Since:
      2.12

    • getLocalThreshold

      public int getLocalThreshold()

      Gets the local threshold. When choosing among multiple MongoDB servers to send a request, the MongoClient 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.

      For example, let's say that the client is choosing a server to send a query when the read preference is ReadPreference.secondary(), and that there are three secondaries, server1, server2, and server3, whose ping times are 10, 15, and 16 milliseconds, respectively. With a local threshold of 5 milliseconds, the client will send the query to either server1 or server2 (randomly selecting between the two).

      Default is 15 milliseconds.

      Returns:
      the local threshold, in milliseconds
      Since:

    • getRequiredReplicaSetName

      @Nullable public String getRequiredReplicaSetName()

      Gets the required replica set name. With this option set, the MongoClient instance will

      1. Connect in replica set mode, and discover all members of the set based on the given servers
      2. Make sure that the set name reported by all members matches the required set name.
      3. Refuse to service any requests if any member of the seed list is not part of a replica set with the required name.

    • isSslInvalidHostNameAllowed

      public boolean isSslInvalidHostNameAllowed()
      Returns whether invalid host names should be allowed if SSL is enabled. Take care before setting this to true, as it makes the application susceptible to man-in-the-middle attacks.

      Default is false.

      Returns:
      true if invalid host names are allowed.

    • getSslContext

      @Nullable public SSLContext getSslContext()
      Returns the SSLContext. This property is ignored when either sslEnabled is false or socketFactory is non-null.

      Since:
      3.5

    • getCodecRegistry

      public CodecRegistry getCodecRegistry()

      The codec registry to use. By default, a MongoClient will be able to encode and decode instances of Document.

      Returns:
      the codec registry
      Since:
      3.0
      See Also:

    • getUuidRepresentation

      public UuidRepresentation getUuidRepresentation()
      Gets the UUID representation to use when encoding instances of UUID and when decoding BSON binary values with subtype of 3.

      The default is UuidRepresentation.UNSPECIFIED, If your application stores UUID values in MongoDB, you must set this value to the desired representation. New applications should prefer UuidRepresentation.STANDARD, while existing Java applications should prefer UuidRepresentation.JAVA_LEGACY. Applications wishing to interoperate with existing Python or .NET applications should prefer UuidRepresentation.PYTHON_LEGACY or UuidRepresentation.C_SHARP_LEGACY, respectively. Applications that do not store UUID values in MongoDB don't need to set this value.

      Returns:
      the UUID representation, which may not be null
      Since:
      3.12

    • getSrvMaxHosts

      @Nullable public Integer getSrvMaxHosts()

      The SRV resource record (RFC 2782) service name, which is limited to 15 characters (RFC 6335 section 5.1). If specified, it is combined with the single host name as follows: _srvServiceName._tcp.hostName. The combined string is an SRV resource record name (RFC 1035 section 2.3.1), which is limited to 255 characters (RFC 1035 section 2.3.4).

      Returns:

      @Nullable public ServerApi getServerApi()
      Gets the server API to use when sending commands to the server.
      Returns:
      the server API, which may be null
      Since:
      4.3

    • getServerSelector

      @Nullable public ServerSelector getServerSelector()
      Gets the server selector.

      The server selector augments the normal server selection rules applied by the driver when determining which server to send an operation to. At the point that it's called by the driver, the ClusterDescription which is passed to it contains a list of ServerDescription instances which satisfy either the configured ReadPreference for any read operation or ones that can take writes (e.g. a standalone, mongos, or replica set primary).

      The server selector can then filter the ServerDescription list using whatever criteria that is required by the application.

      After this selector executes, two additional selectors are applied by the driver:

      • select from within the latency window
      • select a random server from those remaining

      To skip the latency window selector, an application can:

      • configure the local threshold to a sufficiently high value so that it doesn't exclude any servers
      • return a list containing a single server from this selector (which will also make the random member selector a no-op)
      Returns:
      the server selector, which may be null
      Since:
      3.6
