Field Summary

Fields

Modifier and Type	Field and Description
static Option<Integer>	FAILSAFE_CIRCBREAKER_DELAY After opening, a breaker will delay for 1 second(s) by default before before transitioning to half-open.
static Option<Boolean>	FAILSAFE_CIRCBREAKER_ENABLED Enable/disable Circuit breaker failsafe policy (Default: true)
static Option<Integer>	FAILSAFE_CIRCBREAKER_FAILURE_THRESHOLD The number of failures that must occur in order to open the circuit (Default: 3)
static Option<Integer>	FAILSAFE_CIRCBREAKER_FAILURE_THRESHOLDING_CAP The capacity for storing execution results when performing failure thresholding (Default: 5)
static Option<Integer>	FAILSAFE_CIRCBREAKER_SUCCESS_THRESHOLD Configures count based success thresholding by setting the number of consecutive successful transactions that must occur when in a HALF_OPEN state in order to close the circuit, else the circuit is re-opened when a failure occurs.
static Option<Boolean>	FAILSAFE_ENABLED Enable Failsafe integration for Source Query module
static Option<Boolean>	FAILSAFE_RATELIMIT_ENABLED Enable Rate Limiter (Failsafe)
static Option<Long>	FAILSAFE_RATELIMIT_MAX_EXEC Maximum number of executions within the specified period (Default is 650 executions per minute)

static Option<RateLimitType>	FAILSAFE_RATELIMIT_TYPE Specifies the rate limiting method to use (Default is Smooth)
static Option<Long>	FAILSAFE_RETRY_BACKOFF_DELAY Sets the delay between retries (milliseconds), exponentially backing off to the maxDelay and multiplying successive delays by the delayFactor.
static Option<Double>	FAILSAFE_RETRY_BACKOFF_DELAY_FACTOR Sets the delay between retries, exponentially backing off to the maxDelay and multiplying successive delays by the delayFactor.
static Option<Boolean>	FAILSAFE_RETRY_BACKOFF_ENABLED Enable Failsafe's Retry Backoff Feature
