Matthias J. Sax commented on KAFKA-3729:
`configure()` expects `Map configs` but returns `Map`, so the types don't match and you get "unchecked" warning (and warning
fail the build). You would need to add `@SuppressWarning("unckecked")` to the
method to suppress the warning ant to make the build pass.

The following seems to result in compilation error:
{code}
/Users/yute/kafka/streams/src/main/java/org/apache/kafka/streams/KafkaStreams.java:667:
warning: [unchecked] unchecked call to configure(Map,boolean) as a
member of the raw type Serializer

warning: [unchecked] unchecked call to configure(Map,boolean) as a

^
{code}
I wonder how the warnings can be suppressed.
I checked existing calls to configure() which doesn't give me much clue.

[~yuzhih...@gmail.com] It is from the interface `ProcessorContext#appConfigs`, and yes they can be used. Note one tricky thing is that the configs are only passed in at the construction time of the KafkaStreams, whereas the topology is built beforehand, so we can only do the auto-configure at KafkaStreams construction time, not at the topology building time since users are passing in the serde objects. > Auto-configure non-default SerDes passed alongside the topology builder > > > Key: KAFKA-3729 > URL: https://issues.apache.org/jira/browse/KAFKA-3729 > Project: Kafka > Issue Type: Improvement > Components: streams >Reporter: Fred Patton >Priority: Major > Labels: api, newbie > > From Guozhang Wang: > "Only default serdes provided through configs are auto-configured today.

Sax commented on KAFKA-3729: The scope did no change. The "problem" is the following: As you might know, `Serializer` and `Deserializer` have a `configure(Map configs, boolean isKey)` method. Also `Serde` has this method and forwards the corresponding call to the wrapped instances. Furthermore, there are two ways Kafka Streams can use Serdes: they are passed as parameters into operators directly or Kafka Streams creates instances internally based on `StreamsConfig`. For the later case, Kafka Streams calls configure() and passes in a `Map` base on StreamsConfig (cf. `StreamsConfig#defaultKeySerde()` and `StreamsConfig#defaultValueSerde`). However, for the former case the user needs to call configure() in their own code (if it's required to configure a Serde) before they are passed into an operator. Thus, the idea of this ticket is, to lift this requirement. Kafka Streams should call configure() for all Serde objects that are passed into any operator, too, use the same `Map` it passed into `Serde` if it creates them itself. The only thing I am wondering atm is, if `configure()` is supposed to be idempotent? If not, this would be a semantic change and might require a KIP to document the change. Or we might need a config to enable the configuration but don't do it on default to preserve backward compatibility. \cc [~guozhang] > Auto-configure non-default SerDes passed alongside the topology builder > > > Key: KAFKA-3729 > URL: https://issues.apache.org/jira/browse/KAFKA-3729 > Project: Kafka > Issue Type: Improvement > Components: streams >Reporter: Fred Patton >Priority: Major > Labels: api, newbie > > From Guozhang Wang: > "Only default serdes provided through configs are auto-configured today.
