Method Detail

doBackOff

void doBackOff(BackOffFunction.BackOffFuncType funcType,
               Exception err)

doBackOff sleeps a while base on the BackOffType and records the error message. Will stop until max back off time exceeded and throw an exception to the caller.

checkTimeout

void checkTimeout()

check if deadline exceeded.

canRetryAfterSleep

boolean canRetryAfterSleep(BackOffFunction.BackOffFuncType funcType)

canRetryAfterSleep sleeps a while base on the BackOffType and records the error message. Will stop until max back off time exceeded and throw an exception to the caller. It will return false if the total sleep time has exceed some limit condition.

doBackOffWithMaxSleep

void doBackOffWithMaxSleep(BackOffFunction.BackOffFuncType funcType,
                           long maxSleepMs,
                           Exception err)

BackoffWithMaxSleep sleeps a while base on the backoffType and records the error message and never sleep more than maxSleepMs for each sleep.

getSlowLog

SlowLog getSlowLog()

getClusterId

Long getClusterId()
