Arvind Prabhakar commented on FLUME-1244:
-----------------------------------------
Here is my attempt at Load Balancing RPC client. Some details:
* To activate the client, set the property {{client.type}} to
{{default_loadbalance}}.
* It requires that you have at least two hosts specified via {{hosts = h1 h2}}
and {{hosts.h1 = hostname:port}} etc.
* By default it uses a round-robin scheme to distribute load over the various
hosts.
* To change the load distribution scheme to random instead of round robin, set
the value of {{host-selector}} to {{random}}. Otherwise it can be set to
{{round_robin}}.
* To specify your own implementation of host selection algorithm, implement the
interface {{org.apache.flume.api.LoadBalancingRpcClient.HostSelector}}.
* This implementation uses optimistic failover where a failure in handling
event send request will result in the client automatically advancing to the
next available host specified by the selector.
* If all hosts fail, the EventDeliveryException will be raised.

> We now have a load balancing sink processor implemented via FLUME-1198 which
> provides the ability to distribute load over a set of sinks via round/robin
> or random distribution scheme. A similar implementation should be available
> for the RpcClient within the client SDK.
