DynamicClusterDriver

Instance Constructors

new DynamicClusterDriver(timeout: Timeout, maxAttempts: Int)

timeout
The client timeout. It is recommended that this is significantly longer than the cluster failover timeout.
maxAttempts
The number of retries before the driver fails. Should be set greater or equal to the max cluster size.

This counter modulo the cluster size is used to pick a member of the cluster to send leader messages. If we get back a response that the node isn't the leader the driver will increment the counter to try the next node.

Returns an ActorSelection mapped to the passed cluster membership index. This is abstract so that there can be a subclass which knows about cluster membership changes. Counter can be incremented to round-robin to find the new stable leader.
memberIndex
