             Summary: KeyValueStores should not require use of the context's default serializers and deserializers
                 Key: KAFKA-2593
                 URL: https://issues.apache.org/jira/browse/KAFKA-2593
             Project: Kafka
          Issue Type: Sub-task
          Components: kafka streams
            Reporter: Randall Hauch
            Assignee: Randall Hauch
             Fix For: 0.9.0.0


Currently the {{InMemoryKeyValueStore}} is only able to use the key and value serializers and deserializers (aka, "serdes") from the {{ProcessingContext}}. This means that a {{Processor}} implementation that wants to use the {{InMemoryKeyValueStore}} can only do this if the key and value types match those set up as the default serdes in the topology's configuration.

Additionally, the {{RocksDBKeyValueStore}} is only capable of {{byte[]}} keys and values.

Both of these key-value stores should allow the component using them to specify the serdes for both the keys and values. As a convenience, the current behavior should still be supported, as should a way to infer the serdes for the "built-in" serializers and deserializers (e.g., strings, integers, longs, and byte arrays).
