Method Detail

setMaximumPollRateIntervalMilliseconds

public PollerOptions.Builder setMaximumPollRateIntervalMilliseconds(int maximumPollRateIntervalMilliseconds)

Defines interval for measuring poll rate. Larger the interval more spiky can be the load.

setMaximumPollRatePerSecond

public PollerOptions.Builder setMaximumPollRatePerSecond(double maximumPollRatePerSecond)

Maximum rate of polling. Measured in the interval set through setMaximumPollRateIntervalMilliseconds(int).

setBackoffCoefficient

public PollerOptions.Builder setBackoffCoefficient(double backoffCoefficient)

Coefficient to use when calculating exponential delay in case of failures

setBackoffInitialInterval

public PollerOptions.Builder setBackoffInitialInterval(java.time.Duration backoffInitialInterval)

Initial delay in case of regular failure. If backoff coefficient is 1 then it would be the constant delay between failing polls.

setBackoffCongestionInitialInterval

public PollerOptions.Builder setBackoffCongestionInitialInterval(java.time.Duration backoffCongestionInitialInterval)

Initial delay in case of congestion-related failures (i.e. RESOURCE_EXHAUSTED errors). If backoff coefficient is 1 then it would be the constant delay between failing polls.

setBackoffMaximumInterval

public PollerOptions.Builder setBackoffMaximumInterval(java.time.Duration backoffMaximumInterval)

Maximum interval between polls in case of failures.

setBackoffMaximumJitterCoefficient

public PollerOptions.Builder setBackoffMaximumJitterCoefficient(double backoffMaximumJitterCoefficient)

Maximum amount of jitter to apply. 0.2 means that actual retry time can be +/- 20% of the calculated time. Set to 0 to disable jitter. Must be lower than 1. Default is 0.1.

setPollThreadCount

public PollerOptions.Builder setPollThreadCount(int pollThreadCount)

Number of parallel polling threads.

setUncaughtExceptionHandler

public PollerOptions.Builder setUncaughtExceptionHandler(java.lang.Thread.UncaughtExceptionHandler uncaughtExceptionHandler)

Called to report unexpected exceptions in the poller threads.

setPollThreadNamePrefix

public PollerOptions.Builder setPollThreadNamePrefix(java.lang.String pollThreadNamePrefix)

Prefix to use when naming poller threads.
