<p>
+ As of 2.3.0 we've updated how to turn on optimizations. Now, to enable
optimizations, you need to do two things.
+ First, add this line to your properties,
<code>properties.setProperty(StreamsConfig.TOPOLOGY_OPTIMIZATION,
StreamsConfig.OPTIMIZE);</code>, as you have done before.
+ Second, when constructing your <code>KafkaStreams</code> instance,
you'll need to pass your configuration properties when building your
+ topology by using the overloaded
<code>StreamsBuilder.build(Properties)</code> method.
+ For example, <code>KafkaStreams myStream = new
KafkaStreams(streamsBuilder.build(properties), properties)</code>.
+ </p>
+
+ <p>
In 2.3.0 we have added default implementation to <code>close()</code>
and <code>configure()</code> for <code>Serializer</code>,
<code>Deserializer</code> and <code>Serde</code> so that they can be
implemented by lambda expression.
