This KIP will add a new config "enable.topology.optimization" to the StreamsConfig class.  Setting ENABLE_TOPOLOGY_OPTIMIZATION to "trueall" will enable optimization, setting this configuration to "falsenone" or no value at all disables optimization.  The default setting is "falsenone".

public static final booleanString ENABLE_TOPOLOGY_OPTIMIZATION = "enable.topology.optimization" 
private static final String ENABLE_TOPOLOGY_OPTIMIZATION_DOC = "A configuration telling Kafka Streams if it should optimize the topology, falsenone by default"
