Method Detail

maxSize

public ConnectionPoolSettings.Builder maxSize(int maxSize)

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

Default is 100.

Parameters:

maxSize - the maximum number of connections in the pool.

Returns:

this

minSize

public ConnectionPoolSettings.Builder minSize(int minSize)

The minimum number of connections. Those connections will be kept in the pool when idle, and the pool will ensure that it contains at least this minimum number.

Default is 0.

Parameters:

minSize - the minimum number of connections to have in the pool at all times.

Returns:

this

maxWaitQueueSize

public ConnectionPoolSettings.Builder maxWaitQueueSize(int maxWaitQueueSize)

This is the maximum number of waiters for a connection to become available from the pool. All further operations will get an exception immediately.

Default is 500.

Parameters:

maxWaitQueueSize - the number of threads that are allowed to be waiting for a connection.

Returns:

this

maxWaitTime

public ConnectionPoolSettings.Builder maxWaitTime(long maxWaitTime,
                                                  TimeUnit timeUnit)

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

Default is 2 minutes. A value of 0 means that it will not wait. A negative value means it will wait indefinitely.

Parameters:

maxWaitTime - the maximum amount of time to wait

timeUnit - the TimeUnit for this wait period

Returns:

this

maxConnectionLifeTime

public ConnectionPoolSettings.Builder maxConnectionLifeTime(long maxConnectionLifeTime,
                                                            TimeUnit timeUnit)

The maximum time a pooled connection can live for. A zero value indicates no limit to the life time. A pooled connection that has exceeded its life time will be closed and replaced when necessary by a new connection.

Parameters:

maxConnectionLifeTime - the maximum length of time a connection can live

timeUnit - the TimeUnit for this time period

Returns:

this

maxConnectionIdleTime

public ConnectionPoolSettings.Builder maxConnectionIdleTime(long maxConnectionIdleTime,
                                                            TimeUnit timeUnit)

The maximum idle time of a pooled connection. A zero value indicates no limit to the idle time. A pooled connection that has exceeded its idle time will be closed and replaced when necessary by a new connection.

Parameters:

maxConnectionIdleTime - the maximum time a connection can be unused

timeUnit - the TimeUnit for this time period

Returns:

this

maintenanceInitialDelay

public ConnectionPoolSettings.Builder maintenanceInitialDelay(long maintenanceInitialDelay,
                                                              TimeUnit timeUnit)

The period of time to wait before running the first maintenance job on the connection pool.

Parameters:

maintenanceInitialDelay - the time period to wait

timeUnit - the TimeUnit for this time period

Returns:

this

maintenanceFrequency

public ConnectionPoolSettings.Builder maintenanceFrequency(long maintenanceFrequency,
                                                           TimeUnit timeUnit)

The time period between runs of the maintenance job.

Parameters:

maintenanceFrequency - the time period between runs of the maintenance job

timeUnit - the TimeUnit for this time period

Returns:

this

build

public ConnectionPoolSettings build()

Creates a new ConnectionPoolSettings object with the settings initialised on this builder.

Returns:

a new ConnectionPoolSettings object

applyConnectionString

public ConnectionPoolSettings.Builder applyConnectionString(ConnectionString connectionString)

Takes connection pool settings from the given connection string and applies them to this builder.

Parameters:

connectionString - a URL with details of how to connect to MongoDB

Returns:

this
