Class ConnectionRetryConfig
java.lang.Object
com.hazelcast.client.config.ConnectionRetryConfig
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
- 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
When backoff reaches this upper bound, it does not increase any more.- Parameters:
maxBackoffMillis

-
getMultiplier
public double getMultiplier()factor with which to multiply backoff after a failed retry- Returns:
- multiplier

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