> 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).
