ShardingService

ShardingService takes a Distributor where the handle is a service. It uses the distributor to distribute requests *only* when the hash function returns Some[Long]. If None is returned, it throws NotShardableException. If the underlying service for a particular shard is not available, NotServableException is thrown. Example: val serviceFactory = KetamaShardingServiceBuilder() .nodes(services) // services is of type Seq[(String, Service[Req,Rep])] .withHash { req => Some(hashCodeOfSomething)} .buildFactory() val service = serviceFactory() service(req) // where req is a Req and may have ShardableRequest mixed in
