Fault Tolerance Configuration

This page documents all the specific options for the Fault Tolerance EIP.

The Fault Tolerance Configuration eip supports 0 options, which are listed below.

Name	Description	Default	Type
circuitBreaker	Refers to an existing io.smallrye.faulttolerance.core.circuit.breaker.CircuitBreaker instance to lookup and use from the registry. When using this, then any other circuit breaker options are not in use.		String
delay	Control how long the circuit breaker stays open. The default is 5 seconds.	5000	String
successThreshold	Controls the number of trial calls which are allowed when the circuit breaker is half-open.	1	Integer
requestVolumeThreshold	Controls the size of the rolling window used when the circuit breaker is closed.	20	Integer
failureRatio	Configures the failure rate threshold in percentage. If the failure rate is equal or greater than the threshold the CircuitBreaker transitions to open and starts short-circuiting calls. The threshold must be greater than 0 and not greater than 100. Default value is 50 percentage.	50	Integer
timeoutEnabled	Whether timeout is enabled or not on the circuit breaker. Default is false.	false	Boolean
timeoutDuration	Configures the thread execution timeout. Default value is 1 second.	1000	String
timeoutPoolSize	Configures the pool size of the thread pool when timeout is enabled. Default value is 10.	10	Integer
timeoutScheduledExecutorService	References to a custom thread pool to use when timeout is enabled.		ScheduledExecutorService
bulkheadEnabled	Whether bulkhead is enabled or not on the circuit breaker. Default is false.	false	Boolean
bulkheadMaxConcurrentCalls	Configures the max amount of concurrent calls the bulkhead will support.	10	Integer
bulkheadWaitingTaskQueue	Configures the task queue size for holding waiting tasks to be processed by the bulkhead.	10	Integer
bulkheadExecutorService	References to a custom thread pool to use when bulkhead is enabled.		ExecutorService
