Class ConnectionRetryConfig

java.lang.Object

com.hazelcast.client.config.ConnectionRetryConfig

public class ConnectionRetryConfig
extends Object

Connection Retry Config is controls the period among the retries and when should a client gave up retrying. Exponential behaviour can be chosen or jitter can be added to wait periods.

Method Detail

getInitialBackoffMillis

public int getInitialBackoffMillis()

how long to wait after the first failure before retrying

Returns:

initialBackoffMillis

setInitialBackoffMillis

public ConnectionRetryConfig setInitialBackoffMillis(int initialBackoffMillis)

Parameters:

initialBackoffMillis - how long to wait after the first failure before retrying

Returns:

updated ConnectionRetryConfig

getMaxBackoffMillis

public int getMaxBackoffMillis()

When backoff reaches this upper bound, it does not increase any more.

Returns:

maxBackoffMillis

setMaxBackoffMillis

public ConnectionRetryConfig setMaxBackoffMillis(int maxBackoffMillis)

When backoff reaches this upper bound, it does not increase any more.

Parameters:

maxBackoffMillis - upper bound on backoff

Returns:

updated ConnectionRetryConfig

getMultiplier

public double getMultiplier()

factor with which to multiply backoff after a failed retry

Returns:

multiplier

setMultiplier

public ConnectionRetryConfig setMultiplier(double multiplier)

Parameters:

multiplier - factor with which to multiply backoff after a failed retry

Returns:

updated ConnectionRetryConfig

getClusterConnectTimeoutMillis

public long getClusterConnectTimeoutMillis()

Timeout value in seconds for the client to give up to connect to the current cluster Depending on FailoverConfig, a client can shutdown or start trying on alternative cluster after reaching the timeout.

Returns:

clusterConnectTimeoutMillis

setClusterConnectTimeoutMillis

public ConnectionRetryConfig setClusterConnectTimeoutMillis(long clusterConnectTimeoutMillis)

Parameters:

clusterConnectTimeoutMillis - timeout in milliseconds for the client to give up to connect to the current cluster Depending on FailoverConfig, a client can shutdown or start trying on alternative cluster after reaching the timeout.

Returns:

updated ConnectionRetryConfig

getJitter

public double getJitter()

by how much to randomize backoffs. At each iteration calculated back-off is randomized via following method Random(-jitter * current_backoff, jitter * current_backoff)

Returns:

jitter

setJitter

public ConnectionRetryConfig setJitter(double jitter)

At each iteration calculated back-off is randomized via following method Random(-jitter * current_backoff, jitter * current_backoff)

Parameters:

jitter - by how much to randomize backoffs

Returns:

updated ConnectionRetryConfig
