Matthias J. Sax resolved KAFKA-14537.
-------------------------------------
    Resolution: Not A Bug

> Materialized with / as ordering issues
> --------------------------------------
>
>                 Key: KAFKA-14537
>                 URL: https://issues.apache.org/jira/browse/KAFKA-14537
>             Project: Kafka
>          Issue Type: Bug
>          Components: streams
>    Affects Versions: 3.3.1
>         Environment: Java 17
>            Reporter: Matt Allwood
>            Priority: Major
>
> I have found a couple of cases where using Materialized .with and .as in the 
> wrong order can either remove your configured serdes, reverting to the 
> default configured serdes, or remove the store name, reverting to the 
> auto-generated Kafka store name.
> This does not appear to affect .withKeySerde().withValueSerde pairs
> My most recent example is using a simple Processor node followed by a 
> toTable()
> {code:java}
> .process(new PreferenceFlatteningProcessor(PREFERENCE_FLATTENING_STORE_NAME), 
>  PREFERENCE_FLATTENING_STORE_NAME)
>                 .toTable(
>                         Materialized
>                          
> .with(avroSerdes.commodityRegionValuesWithCLKeySerde, Serdes.Integer())
>                          .as("flattenedUserPreferencesTable"))
>  {code}
> (apologies for formatting - it's difficult to see in JIRA)
> Having the .as in the above resulted in toTable failing as it tried to use 
> the default serdes rather than those provided. It was a confusing bug, as the 
> error suggested that the issue was in my .process() code in serialising the 
> record rather than in the following toTable().
> As mentioned I have also encountered issues with the names going missing, but 
> didn't raise that at the time, as it was an annoyance rather than crashing my 
> application.
