Randall Hauch commented on KAFKA-2593: -------------------------------------- ~guozhang, I've replaced the static factory methods in each of the key-value store implementations with a builder class. (See the PR for details.) > 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). -- This message was sent by Atlassian JIRA (v6.3.4#6332)
