Package com.hazelcast.client.config

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.

    • 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 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 clusters after reaching the timeout. If it is equal to -1, which is the default value, the client will not stop trying to connect to the cluster. If the failover client is used, for the default value, the client will start trying to connect alternative clusters after FAILOVER_CLIENT_DEFAULT_CLUSTER_CONNECT_TIMEOUT_MILLIS. For any other value, both the failover and non-failover client will use that as it is.
      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 clusters after reaching the timeout. If set to -1, which is the default value, the client will not stop trying to connect to the cluster. If the failover client is used, for the default value, the client will start trying to connect alternative clusters after FAILOVER_CLIENT_DEFAULT_CLUSTER_CONNECT_TIMEOUT_MILLIS. For any other value, both the failover and non-failover client will use that as it is.
      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
