[jira] [Created] (KAFKA-16458) Add contains method in KeyValue store interface

Ayoub Omari created KAFKA-16458:
-----------------------------------

             Summary: Add contains method in KeyValue store interface
                 Key: KAFKA-16458
                 URL: https://issues.apache.org/jira/browse/KAFKA-16458
             Project: Kafka
          Issue Type: Wish
          Components: streams
            Reporter: Ayoub Omari


In some stream processors, we sometimes just want to check if a key exists in the state store or not.

 

I find calling .get() and checking if the return value is null a little bit verbose
{code:java}
if (store.get(key) != null) {

}{code}
 

But I am not sure if it is on purpose that we would like to keep the store interface simple.
