All Implemented Interfaces:

Consumer<Supplier<Iterator<PooledConnectionProxy>>>, Freezable, PruneStrategy

public class IdlePruneStrategy
extends AgePruneStrategy

Removes connections from the pool based on how long they have been idle in the available queue. By default, this implementation executes every 5 minutes and prunes connections that have been idle for more than 10 minutes. This strategy will not prune available connections below the minimum pool size unless an age time is configured. Connections will be pruned by age before they are pruned by idle time.

Field Details

DEFAULT_IDLE_TIME

private static final Duration DEFAULT_IDLE_TIME

Default idle time. Value is 10 minutes.

idleTime

private Duration idleTime

Idle time.

Constructor Details

IdlePruneStrategy

public IdlePruneStrategy()

Creates a new idle prune strategy.

IdlePruneStrategy

public IdlePruneStrategy(Duration idle)

Creates a new idle prune strategy. Sets the prune period to half of the supplied idle time.

Parameters:

idle - time at which a connection should be pruned

IdlePruneStrategy

public IdlePruneStrategy(Duration period,
 Duration idle)

Creates a new idle prune strategy.

Parameters:

period - to execute the prune task

idle - time at which a connection should be pruned

IdlePruneStrategy

public IdlePruneStrategy(Duration period,
 Duration idle,
 Duration age)

Creates a new idle prune strategy.

Parameters:

period - to execute the prune task

idle - time at which a connection should be pruned

age - time at which a connection should be pruned

Method Details

getPruneConditions

public List<Predicate<PooledConnectionProxy>> getPruneConditions()

Description copied from class: AbstractPruneStrategy

Returns the predicates used by this prune strategy. Each predicate will be invoked for every connection to be pruned.

Overrides:

getPruneConditions in class AgePruneStrategy

Returns:

List of predicates that are evaluated in order. Connections are removed from the pool immediately upon predicate returning true; subsequent predicates operate on a reduced pool.

getStatisticsSize

public int getStatisticsSize()

Description copied from interface: PruneStrategy

Returns the number of statistics to store for this prune strategy. See PooledConnectionStatistics.

Specified by:

getStatisticsSize in interface PruneStrategy

Overrides:

getStatisticsSize in class AgePruneStrategy

Returns:

number of statistics to store

getIdleTime

public Duration getIdleTime()

Returns the idle time.

Returns:

idle time

setIdleTime

public void setIdleTime(Duration time)

Sets the idle time.

Parameters:

time - that a connection has been idle and should be pruned

toString

public String toString()

Overrides:

toString in class AgePruneStrategy

builder

public static IdlePruneStrategy.Builder builder()

Creates a builder for this class.

Returns:

new builder
