retryNone

DEFAULT_ONE_HOUR_TIMEOUT

public static final long DEFAULT_ONE_HOUR_TIMEOUT

Method Detail

retryNetworkErrors

public static Predicate<Throwable> retryNetworkErrors()

Check all known network exceptions

Returns:

predicate for checking all network exceptions

retryTarantoolNoSuchProcedureErrors

public static Predicate<Throwable> retryTarantoolNoSuchProcedureErrors()

Check TarantoolNoSuchProcedureException

Returns:

predicate for checking TarantoolNoSuchProcedureException

byNumberOfAttempts

public static TarantoolRequestRetryPolicies.AttemptsBoundRetryPolicyFactory.Builder<Predicate<Throwable>> byNumberOfAttempts(int numberOfAttempts)

Create a factory for retry policy bound by retry attempts. The retry will be performed on any known network exceptions.

Parameters:

numberOfAttempts - maximum number of retries, zero value means no retries

Returns:

new factory instance

byNumberOfAttempts

public static <T extends Predicate<Throwable>> TarantoolRequestRetryPolicies.AttemptsBoundRetryPolicyFactory.Builder<T> byNumberOfAttempts(int numberOfAttempts,
                                                                                                                                           T exceptionCheck)

Create a factory for retry policy bound by retry attempts

Type Parameters:

T - exception checking predicate type

Parameters:

numberOfAttempts - maximum number of retries, zero value means no retries

exceptionCheck - predicate, checking the given exception whether the request may be retried

Returns:

new factory instance

unbound

public static <T extends Predicate<Throwable>> TarantoolRequestRetryPolicies.InfiniteRetryPolicyFactory.Builder<T> unbound()

Create a factory for retry policy with unbounded number of attempts. retryNetworkErrors() is used for checking exceptions by default.

Type Parameters:

T - exception checking predicate type

Returns:

new factory instance

unbound

public static <T extends Predicate<Throwable>> TarantoolRequestRetryPolicies.InfiniteRetryPolicyFactory.Builder<T> unbound(T exceptionCheck)

Create a factory for retry policy with unbounded number of attempts

Type Parameters:

T - exception checking predicate type

Parameters:

exceptionCheck - predicate, checking the given exception whether the request may be retried

Returns:

new factory instance
