             Summary: Improve Documentation on usage of Materialized config object
                 Key: KAFKA-8666
                 URL: https://issues.apache.org/jira/browse/KAFKA-8666
             Project: Kafka
          Issue Type: Improvement
          Components: documentation, streams
            Reporter: Bill Bejeck


When using the Materialized object if the user wants to name the statestore with
{code:java}
Materialized.as("MyStoreName"){code}
then subsequently provide the key and value serde the calls to do so must take the form of 
{code:java}
Materialized.as("MyStoreName").withKeySerde(keySerde).withValueSerde(valueSerde)
{code}
If users do the following 
{code:java}
Materialized.as("MyStoreName").with(keySerde, valueSerde)
{code}
the Materialized instance created by the "as(storeName)" call is replaced by a new Materialized instance resulting from the "with(...)" call and any configuration on the first Materialized instance is lost.
