Method Detail

maxThreadPoolSize

public ThreadPoolBulkheadConfig.Builder maxThreadPoolSize(int maxThreadPoolSize)

Configures the max thread pool size.

Parameters:

maxThreadPoolSize - max thread pool size

Returns:

the BulkheadConfig.Builder

coreThreadPoolSize

public ThreadPoolBulkheadConfig.Builder coreThreadPoolSize(int coreThreadPoolSize)

Configures the core thread pool size.

Parameters:

coreThreadPoolSize - core thread pool size

Returns:

the BulkheadConfig.Builder

contextPropagator

public final ThreadPoolBulkheadConfig.Builder contextPropagator(@Nullable
                                                                java.lang.Class<? extends ContextPropagator>... contextPropagatorClasses)

Configures the context propagator class.

Returns:

the BulkheadConfig.Builder

contextPropagator

public final ThreadPoolBulkheadConfig.Builder contextPropagator(ContextPropagator... contextPropagators)

queueCapacity

public ThreadPoolBulkheadConfig.Builder queueCapacity(int queueCapacity)

Configures the capacity of the queue.

Parameters:

queueCapacity - max concurrent calls

Returns:

the BulkheadConfig.Builder

keepAliveDuration

public ThreadPoolBulkheadConfig.Builder keepAliveDuration(java.time.Duration keepAliveDuration)

When the number of threads is greater than the core, this is the maximum time duration that excess idle threads will wait for new tasks before terminating.

Parameters:

keepAliveDuration - maximum wait duration for bulkhead thread pool idle thread

Returns:

the BulkheadConfig.Builder

writableStackTraceEnabled

public ThreadPoolBulkheadConfig.Builder writableStackTraceEnabled(boolean writableStackTraceEnabled)

Enables writable stack traces. When set to false, Throwable.getStackTrace() returns a zero length array. This may be used to reduce log spam when the circuit breaker is open as the cause of the exceptions is already known (the circuit breaker is short-circuiting calls).

Parameters:

writableStackTraceEnabled - flag to control if stack trace is writable

Returns:

the BulkheadConfig.Builder

build

public ThreadPoolBulkheadConfig build()

Builds a BulkheadConfig

Returns:

the BulkheadConfig
